Dave Micklos, D.Sc.

Executive Director

Nothing in my precollege schooling in a leafy suburb of Baltimore would have predicted that I would end up at a high-powered research institute. I sat in the back row of biology class, where I regularly played cards. I often slept during my chemistry class because I stayed up late to watch the Dick Cavett Show. However, I got turned on to biology in a sophomore class at Frostburg State College, when I did a great dissection of the inner ear of a sand shark and debated the professor on her labeling of the parts on a practical. I also had an assistantship to help out on research on sea squirts and got hooked on bird watching. After completing an undergraduate degree in biology, I did service in the Peace Corps as a secondary science teacher at a government boarding school on the edge of the Kalahari Desert in Botswana. I returned to get a graduate degree in journalism, but my dream of becoming a science writer was dashed by a sharp downturn in science reporting in daily newspapers.

After a brief stint in opinion research at a Manhattan PR agency, I was hired by Jim Watson in 1982 to start the Laboratory’s development and public affairs efforts.  However, when Jim was away on sabbatical in 1984, I became increasingly interested in education. Future Nobel Laureate, Rich Roberts, gave me a little space in his lab, where I worked with postdoc Greg Freyer to develop a set of simple experiments that would allow students to get their hands dirty with recombinant DNA. By the time Jim returned from England, I had managed to raise $60,000 to equip six local school districts for DNA experimentation and to train the first group of Long Island teachers.

By summer 1986, we had a spiffy “Vector Van,” loaded to the ceiling with pipets, centrifuges, and water baths, which we took on a nationwide training tour that ended at the University of California at Davis. In 1987 we won our first grant from the National Science Foundation, acquired a second Vector Van, and conducted workshops at 14 locations around the country. By this time it was clear to Jim that our DNA education program had to conform to his dictum of organizational evolution: “You get bigger, or you get smaller.” So he determined that we should take over an abandoned elementary school on Main Street in Cold Spring Harbor Village. The Laboratory trustees were worried that a “DNA museum” might be a little frumpish, and perhaps overly focused on Jim, so we came up with “DNA Learning Center.”

Of course, none of us really understood what a DNA Learning Center (DNALC) might entail, and we only had about half of the first year’s lease funds in hand. Nevertheless, by spring 1988 we conducted the first lab field trips during which students dissected viral DNA or inserted an antibiotic resistance gene into bacteria. Thus, we became the first place in the world to routinely do DNA manipulation experiments with precollege students. Since that time, more than 400,000 students have performed these and other experiments at the DNALC without mishap, proving the relative safety of DNA methods.

Now, I spend most of my time writing grants and looking after the DNALC’s $4 million annual budget and staff of 25. I devote a lot of energy to developing computer infrastructures that can allow large numbers of students to work independently with biological data. The DNALC has thrived and evolved for 30 years, so I suppose it will survive another 30.

Lindsay Barone, Ph.D.

Evaluation Consultant

Growing up I was always interested in science. Whether it was paleontology, geology, anatomy, or chemistry, I was a kid who wanted to understand what was going on in the world around me. However, it wasn't until I was in my first semester of college, sitting in a class called "Evolution and Extinction," that I realized what I wanted to study. The next four years at the University of Wisconsin were spent studying human evolution, learning about the biological and cultural aspects of our species and our place in the natural world.


Out of college, I took an unusual career detour. Instead of going to graduate school or getting a job in my field, I spend the year driving the Oscar Mayer Wienermobile around the country. As a part of this tour I had the opportunity to visit science centers and natural history museums nationwide and it was during this year that I realized that working in these kinds of institutions was what I wanted for a career. So, I made it happen! I was accepted into the University of Wisconsin-Milwaukee and Milwaukee Public Museum's joint anthropology and museum studies graduate program, and eventually earned a master's degree in anthropology, a graduate certificate in museum studies, and a doctorate in anthropology with a minor in biology.

In the years since I began graduate school, I've held a number of positions. I've worked in libraries, historical museums, natural history museums, and taught at a few different universities. I've done extensive research on how people learn science outside of the classroom and I've examined how visitors respond to scientific concepts in a museum setting. Most importantly, I've become quite interested in learning how science centers can be used to increase science literacy in the general public. As the evaluator at the DNA Learning Center, I use my expertise to examine our programs, exhibits, and other educational elements of our centers in New York and around the world.

Louise Bodt

High School Educator

I fell in love with science when I was about 7 years old and we learned about the Cretaceous-Paleogene mass extinction in school. As a kid growing up in New York City, I looked for any opportunity to immerse myself in the scientific community. I found myself at the American Museum of Natural History where I took classes and participated in internships throughout high school and college. This is where I took my first molecular biology class in the Hall of Human Origins lab and learned about DNA, Rosalind Franklin and genetics. It was after this class I decided that I wanted to study DNA.

Once at college I studied biochemistry and molecular biology and worked in a parasitology and genetics lab, I participated in research on Brugia malayi and other nematodes, murine gut metagenomics and human genetics. After graduation, I taught science at a private school in NYC where I gained experience teaching and developing curricula in a formal classroom setting.

After spending so much time as a student at the AMNH, I joined the team as a teaching assistant for classes and camps, eventually becoming an instructor for biology and paleontology workshops and research classes for pre-K-12th grade. Connecting with scientists and educators at the AMNH helped me develop my passion for evolutionary biology and population genetics. For my master’s thesis I worked on a project studying the genetics of the North American population of European starlings and comparing them with other introduced populations world-wide. I continue to work on using starlings to teach us about evolution and look at population genetics of different species of fish from NYC waterways.

As a native-Brooklynite, biologist, educator and DNA-enthusiast, when the DNA Learning Center in Brooklyn opened, I knew I had to be part of this amazing community! I am so excited to be participating in the Urban Barcode Project and engaging in molecular biology and genetics all around NYC. I look forward to the opportunity to do research with students and use DNA everyday!

Justin Burke

Lab Assistant

I was born and raised on Long Island. For as long as I can remember I have always been interested in science. As a child I was fascinated by anything to do with space. I would always sit in my backyard staring at the sky wondering what was out there. It wasn’t until much later on that I would become interested in Biology. My high school didn’t require me to take a science course my last two years in order to graduate and so I kind of lost interest in science. It was always in the back of my mind and I would still watch some of those science shows on TV (this was the time that you could actually discover things on the Discovery Channel and learn things on The Learning Channel) but that was the extent of it.

When I graduated high school I went to Suffolk Community College for business management which I quickly learned I didn’t like and so I quit after a year. I concentrated on my job at a cleaning company after that and eventually became the Operations Manager which I enjoyed for a few years but I never really felt fulfilled. In desperate need of a change, I left there and moved to Cape Coral, Florida. It was there that I would rediscover my passion for science that I had when I was a little kid. The night sky looked like nothing I’d ever seen before (there’s too much light pollution on Long Island). Again I found myself sitting outside staring at the night sky which inspired me to start reading Carl Sagan and Anne Druyans ‘A Pale Blue Dot’. When I finished that I was hooked again and I started reading, watching, and listening to everything about science I could get my hands on. At the time this was just a hobby of mine and I had no intention of making it a career. Eventually the heat in Southwest Florida became too much and so I moved back to NY after about eight months.

Struggling to find a job outside of the cleaning industry I decided to go back to school to get my degree which I always regretted not finishing. In my second semester back I took a physical anthropology course which was my first real introduction to genetics and biology in college. After about a year and a half, I graduated from Suffolk and enrolled in Stony Brook University studying biochemistry and cell biology. That eventually led me to getting a job at the DNA Learning Center and I couldn’t be happier professionally.

Elna Carrasco-Gottlieb

Middle School Educator

My first visit to the American Museum of Natural History in New York was when I was five years old.  As I walked through the halls of dinosaurs on the fourth floor, I felt as though I was meeting old friends.  Most little girls might run from the 15 ft tall skeleton of T-Rex, but I thought he was beautiful.  That was the beginning of my love affair with science.  I became fascinated with the world, the universe, and the evolution of all living things.

I received a Bachelor's degree in Earth & Space science with a Biology Concentration and my NYS Secondary Science Teaching Certification.  In my graduate studies, in the department of Ecology and Evolution at Stony brook University; I worked with my mentor, Dr. Catherine Forster, who is an expert in dinosauria. We related environment to predator-prey ratios on fossils from the Judith River Formation in Montana.  This is how I became pretty good at identifying dinosaurian teeth (my favorite tooth was from a fetal stegosaurus – it was smaller than a caraway seed and looked like a flower under the stereoscope). 

In 2000, my search for adventure led me to Cold Spring Harbor Laboratory's DNA Learning Center, where I began as a Middle School Educator. What an adventure it has been!  I traveled to Singapore to train teachers, and I was also able to conduct research in Belgium and Italy for our new exhibit featuring a 3D printed replica of Ötzi the Iceman.  I have created new lab experiences and week-long workshops, ranging from genetic engineering to forensic science, for local and international students. 

Ever since I entered the front entrance of the little “school house” on 334 Main Street, Cold Spring Harbor, I have been exploring the question "How did we get here" through the doorway of evolution. The key to this doorway is in our own DNA. What a wonderful place to learn the secrets of life while sharing our knowledge with the future of our world, our children!

Megan Capobianco

Middle School Educator

Unlike most of the biographies you will read on this site, I did not develop my love for science until I was much older. My family looks at my passion for the field now and wonders “Where did you come from?” I can’t exactly pinpoint the moment my interest sparked, but it was most likely after the Planet Earth series aired, so a big thanks to David Attenborough’s mesmerizing voice for igniting my fascination of wildlife conservation. From there on out, I wanted to learn everything I could about biology, ecology, evolution, and more.

I graduated from SUNY Geneseo with a bachelor’s in Childhood and Special Education. After getting my degree I moved to Miami for the opportunity to teach (and for the beaches). Instead of being given an elementary class, I was thrown into the middle school to teach science. Although I minored in Environmental Science I was completely intimidated. However, after a few weeks I could no longer imagine myself teaching anything other than science–I loved it! My favorite part of teaching science was seeing the curiosity and excitement on my students’ faces during labs and hands-on activities.

While getting my master’s degree in Environmental Policy and Management I had the privilege of interning with the NYS Department of Environmental Conservation. We surveyed juvenile striped bass in the western bays of Long Island, which included Cold Spring Harbor. From the harbor I would admire the laboratory and the amazing research being conducted there. I’m excited to have moved back to Long Island and to work at CSHL’s DNA Learning Center with such an inspiring group of people!

Lauren Correri

Assistant Administrative Manager

I was born on Long Island and raised mostly on Long Island, save for a five year stint in northern Virginia during my teens, but since northern Virginia is full of people fleeing the Tri-State area I hardly noticed the difference. I graduated from high school in Virginia and returned to Long Island to attend college. I received my bachelor's degree in history from Adelphi University. I then moved on to Sarah Lawrence College for a master's in Women's History, but life got in the way. I plan to resume someday: in the meantime I'm continuing research on my thesis.

Career-wise, I've worked in an administrative capacity for a firm specializing in background investigations and an insurance agency. In the future, I'd like to either teach or work in a museum setting, so working here at the DNALC, which has elements of both, is really wonderful to me.

In my free time, I read, write, draw and make occasional stabs at knitting. I'm also trying to teach my bratty German Shepherd, Emma, how to behave herself in polite society: so far it's not working. I'm also working on improving my Japanese: maybe this year I'll memorize enough kanji to be able to read on a fifth-grade level. Ganbaru yo!

Heather Cosel-Pieper

Lab Instructor

"That was so cool," I remember thinking as I walked out of the DNA Learning Center and back onto my bus. Having grown up nearby, I was lucky enough to visit the Learning Center as part of my high school biology curriculum in the early nineties. It was my first exposure to bench science, and I believe it is what really got me interested in research.

I maintained this interest through AP Bio, and decided to major in molecular and cellular biology at NYU. Each summer during my undergrad, I returned to CSHL—first as an intern and later as a member of the Undergraduate Research Program (or URPs as they're known around campus). Although I enjoyed bench work, I decided that it was not my calling, and so I looked for more of a molecular biology office job. That's how I ended up in scientific publishing.

From 2000-2016, I worked in the editorial department of a peer-reviewed research journal that is published by the Laboratory's Press. I enjoy the communication of science—whether it be from one researcher to another (through manuscripts), or from researchers to a wider audience (through press releases). I now focus exclusively on students, who I hope will also walk away from the Learning Center with some appreciation of how cool modern molecular biology can be, and how relevant it is to our everyday life.

Cristina Fernandez Marco, Ph.D.

High School Educator

I grew up in a beautiful coastal town called Santander in Northern Spain where there are amazing mountains, green lands (it rains a lot), and pristine beaches. Santander is in the province of Cantabria, which is unofficially known as "Cantabria Verde", or "Green Cantabria".  If you look at any of the pictures of Cantabria, you can see why we had no choice but to love nature. My parents were born in different remote villages of the same province, so we were lucky to spend a lot of weekends and summers in the greenery that surrounded the city. I guess it is pretty obvious what my favorite color is.

I studied in the University of Malaga, and majored in Biology. During those years, I hiked a lot – pretty much every weekend and I realized that plants are one of the most interesting organisms to study: they make oxygen for our planet, they are able to evolve and adapt with their roots attached – how cool is that? Their diversity is amazing, and they manage to reproduce using insects, wind, and humans.

I did my Ph.D. in Plant Pathology studying the genetic diversity of viruses affecting major crops on the Southeastern region of Spain. I became really good at using white flies as vectors for the viruses.

Fast forward a few years, I moved to Cold Spring Harbor Laboratory as a postdoctoral fellow. This time I chose to work on basic research using model organisms. Arabidopsis thaliana and maize helped me to characterize mutants affecting leaf and embryonic development.

Where does my education fit into the world of teaching? My father was a middle school teacher, and ever since I can remember teaching has been a very big part of my life. While I was in high school and college, during the summer sessions I learned a lot by helping my father tutor his students.  When I moved to the United States, I taught genetics and biology at a number of colleges and universities in New York City and Long Island.

Now in 2015, I am very proud to be a part of the Cold Spring Harbor Laboratory DNA Learning Center making science accessible to the general public. On a personal note this is also the year my son Rohan was born. More celebrations!

Cornel Ghiban

Senior Software Developer

I have an engineering degree from Technical "Gheorghe Asachi" University, Iasi, Romania where I studied computer science and engineering. I have been designing and writing software since 2000, primarily in Perl since I like its flexibility and powerful features. I enjoy creating online web applications because the impact is immediate and people have access to its features as soon as I publish them. You can also continuously improve and add features to your app. It is almost an organic experience.

Another dimension to my work is the focus on open source technologies. I love the feeling when your work is part of a project that brings together some of the best minds in an area. It is amazing to me howa virtual team gets to create and improve upon a project and make something very useful to the entire community.

Jennifer Hackett, Ph.D.

High School Educator

I grew up in Ohio and spent most of my childhood building tree houses in the woods and riding bikes. I had very little idea of what I wanted to be when I grew up, and no one in my family had a career in science. In school, I loved logic puzzles but didn’t realize that science is all about solving puzzles until high school. In 9th grade, we almost exclusively conducted experiments in science class and I was amazed to discover that we could figure out the nature of atoms for ourselves, even though we couldn’t see them. That experience gave me a new way to think about the world.

I studied genetics in college because I enjoyed the logic and because I appreciated being able to do research that might help cure diseases. At the time, the Human Genome Project was still years away from completion and the hunt for a single disease gene might take a team of scientists 10 or more years. I was lucky enough during a college internship at the Mayo Clinic to have the opportunity to make a very small contribution close to the end of a hunt for a gene for frontotemporal dementia. This experience gave me a deep appreciation of the vastness of the human genome and the myriad ways that changes in DNA may or may not cause disease.

Because I was hooked by genetics, I joined the Human Genetics and Molecular Biology graduate program at Johns Hopkins University School of Medicine. In Carol Greider’s lab, I studied how the shortening of the repetitive telomere sequence at the ends of chromosomes can lead to rearrangements of other parts of the chromosomes. These kinds of mutations can cause cancer. This was the most complex puzzle I had yet encountered and I loved every moment of it. I also greatly enjoyed my postdoctoral research at Harvard Medical School developing a high-throughput way to turn off individual human genes to screen for genes that could be possible drug targets.

In my free time, I was increasingly volunteering with children and discovered that I was even happier working with children than I was in the research lab. I studied to be an educator and am happy to have taught science in NYC schools for 13 years. Figuring out the best strategy to develop each student’s understanding is an ever-evolving puzzle. I am thrilled to join the DNALC for the opportunity to combine my passions for science and education and to support the next generation in developing a love for learning.

Daniel Jacobs


I have a degree in computer science from Queens College. My interest in coding began in high school, where I took courses which taught me about front end web development. I took this knowledge into the first college I attended, Adelphi University, where I worked on the university web team as a student worker. I was studying physics at Adelphi University, and during my last semester there, I developed a passion for programming while taking both an introductory computer science course and a physics elective about the programming language MATLAB.

I learned many more programming languages once I transferred to Queens College, and tutored other students both through the computer science department and privately. I learned Python in order to help a physics professor at Queens College with his research on measuring the impact of certain factors on the sustainability of world peace. I am now working in the BioMedia Group at Cold Spring Harbor Laboratory to develop tools to aid students in learning the many topics taught in the DNA Learning Center.

Brittany Johnson

Middle School Educator

Years ago, while volunteering in the then Central Islip School District (CISD) Mulligan Science Center, a DNA Learning Center Educator came to do a lab with a number of students. After explaining my background, I inquired if I could teach one of the classes. Little did I know my first lecture taught on that day would become one of many.

As a child, I was inquisitive and observant, and read incessantly; so much so the loss of my library card brought on tears. I had a strong interest in music and science, and an overall love for learning and the outdoors. Early exposure to hospitals and medicine focused my interest on living things, and how they live without having to think to do so, because of the internal dance that occurs. I also wanted to understand the human body, and the states of both ease and “dis-ease” that we experience. In short, I wanted to know how things tick, and how to fix the clock if something affected its ability to tell time.

Looking back, I remember visiting the DNA Learning Center as a child and being captivated by the Anastasia Lab. I love mysteries, and so solving a case through science expanded my curiosity about DNA and heredity. I liked that there was order to the variation, a sort of biological cause to each effect. I then participated in a Summer DNA Program creating antibiotic resistant genes held at Central Islip High School, and am grateful for my own teachers, who made sure we had the opportunity and exposure to this style of learning. I graduated with an Advanced Regents Diploma, and then went on to receive a Bachelor of Arts in Biology from Fisk University, and a Master of Biological Medical Sciences from Mississippi College.

Sometimes I reflect on when I used to worry about making the right decision regarding my future career when I was younger. When you have so many interests, how do you decide on just one? Being here has reminded me of this question, and provided an answer. Thanks to the varied backgrounds of my fellow educators, each day comes with the opportunity to learn something new in a field different than my own, and I am so grateful to be able to experience it.

The DNA Learning Center sparked an interest I never forgot, and driving up to the building felt like returning home. As an educator, it is my aspiration to encourage critical thinking, while creating an environment and an excitement for learning. To be able to help ignite a small part of that for the next generation, to me, is everything.

Born and raised in rural Ontario, Canada, I moved to Long Island with my family when my father became Professor of Family Medicine at SUNY Stony Brook.

My administrative work has taken several interesting paths, from music management and entertainment booking agencies to magazine publishing and insurance-related companies. I have also assisted my husband, a photographer, with his varied and exciting projects.

Through the years at the DNA Learning Center West, I have expanded my duties to include conducting Northwell Health Clinical Core Lab student tours, as well as coordinating lab reservations for all of our locations.

It is an honor for me to support the DNALC team, imparting important knowledge to future generations.

Susan Lauter

Creative Director

I started at CSHL after my junior year at the Cooper Union for the Advancement of Science and Art as a summer photography intern in the Public Affairs department. I spent my time wandering the grounds photographing the beautiful landscapes and architecture, popped into labs to capture candids of the scientists at work, documented the activities of the meetings and courses, and designed publications and brochures. I stayed on through my senior year, splitting my weeks between the CSHL campus and NYC's East Village. After graduating with a BFA in 1986, I was hired full time that fall. I am always proud when I recognize my photos from that time in Lab publications!

I transitioned to the DNALC a year after it opened in 1989 to be an Exhibit Designer, and I got married a few months later. Over the years, I took on additional and varied responsibilities and I am now the Creative Director. I helped develop our in-house exhibits Story of a Gene (1995), The World of Barbara McClintock (1996), The Genes We Share (2002), and the current exhibition featuring Ötzi the Iceman, Our Human Inheritance (2016). I worked with the BioMedia Group to develop our suite of digital resources, including 20+ websites and three apps. I illustrated the textbooks DNA Science (1990) and Laboratory DNA Science (1996), and created the cover of Genome Science (2013). The BioMedia Group also creates printed materials including posters and banners, brochures, exhibit guides, and flyers, as well as produces webinars and videos. I still wander with a camera, capturing visiting students working in our lab and computer classrooms.

My role is ever evolving. I have been fortunate for nearly three decades to use art to advance the understanding of science at the DNALC and work with and support its amazing science educators.

My husband Marty and I raised three children, now all adults: Ryan followed in my wandering footsteps and now holds a BFA in photography; Marty earned a BFA in Musical Theatre; and Casey has a BS in Kinesiology/Exercise Science and intends to continue her education to be a Physician Assistant. So, the advancement of art and science continues in our family's next generation!

Melissa Lee

Harlem DNA Lab Manager

My first memorable experience of science began with an experiment on diapers since my younger sister's consumption of them was becoming a legitimate family issue. To me, such an experiment seemed practical, yet not as sophisticated as my fellow 7th graders' experiments. To my surprise, my diaper project was one of the only two projects entered in the Bronx Borough Science Fair and it was the first time that I felt a certain sense of pride in my abilities as a future scientist.

As a high school student I was given the opportunity to work in a lab at Rockefeller University and be a member of the Pre-college Science Collaborative at the American Museum of Natural History. It was at the Museum that I took a Cold Spring Harbor course called "DNA Science" and was introduced to DNA recombinant technology. I remember working with pipettors and seeing DNA in gels for the first time and thinking how cool it was to manipulate DNA. This exposure, along with my experience at Rockefeller University propelled me forward in pursuing a science career.

At Johns Hopkins University I double majored in Biology and Art History and worked in a lab that studied mouse models of Down Syndrome. It was an exciting time, since the Human Genome Project was currently underway and our lab was elucidating the sequence of mouse chromosomes that are homologous to Human Chromosome 21 involved in Down Syndrome. After college I worked in a Developmental Genetics lab that was investigating the spatial and temporal expression of genes in early mouse development.

Years later, I started thinking that perhaps my actual niche would be in science education. I became a NYC teaching fellow and taught at The Marie Curie School for Medicine, Nursing and Health Professions for a number of years. At Marie Curie, I taught various courses, including Living Environment, Forensic Science, and Anatomy.

When a job opening for the Harlem DNA Lab Manager became available, I was drawn to this position because it encompasses all of who I believe myself to be as both a scientist and an educator. I get to teach my favorite topic, genetics, and I get to do that in my hometown of New York City.

Allison Mayle, Ph.D.

High School Educator

In elementary school, one of my teachers put a petri dish of water on the overhead projector and asked us to think about why the water “disappeared”. I have a distinct memory of the moment when I realized that the water molecules got warm because of the light bulb and didn’t want to be near each other anymore, so they spread out and turned into gas! From then on, I was fascinated by the idea of science as a process of figuring out why and how things worked, and I took every science class I could in high school.

I attended Michigan State University in large part because of the opportunity to do research starting as a freshman through the Professorial Assistantship program. I really enjoyed working in the lab, so I applied to Ph.D. programs and landed in the Molecular and Human Genetics program at Baylor College of Medicine in Houston. In grad school, I studied the processes that control stem cell self-renewal (making more stem cells to maintain a pool throughout life), and how these processes go awry in blood cancers. This was an exciting time as CRISPR was coming on to the scene as a new method for gene editing, so I started working with this technique. I then moved on to a postdoc position at Memorial Sloan Kettering Cancer Center, where I continued to use CRISPR and study leukemia.

During my time in Houston I volunteered for programs that introduced high school students to careers in science and medicine, and at the Health Museum in the DeBakey Cell Lab where I guided visitors through a variety of science experiments. It wasn’t until I was interviewing to be a Scientist-in-Residence in NYC that I realized I was more invested in making science accessible to non-scientists than I was in doing primary research myself.

When I came across the DNA Learning Center, I knew that this was a place where my firm belief that science is for everyone was shared. I found out that they wanted to develop a CRISPR course and would be hiring Educators and applied immediately! I’m excited to spend more of my time teaching and sharing science with students.

Amanda McBrien

Assistant Director

Growing up, I was always surrounded by animals. There was my brother's pet rat, the family turtle and bird, and of course the dogs. There were always dogs! In fact, every year we had a new puppy because we are "puppy walkers" for the Guide Dog Foundation for the Blind. My family has raised puppies since I was in 6th grade, and also participated in the breeding program -- having 2 litters of Labrador Retreiver pups right in our computer room! This constant exposure brought out the animal lover in me, and I decided early on that I was going to be a veterinarian.

I most enjoyed classes in zoology, physiology and animal behavior during my undergraduate biology work at the State University of New York at Stony Brook. After two years of trying to get into veterinary school, I decided to move on with my life. I had to make a decision. What can I do with a degree in biology, and no interest in becoming a lab technician? Teaching was a logical, and surprisingly easy transition for me. I suppose all those years of teaching Sunday school have finally paid off!

Teaching at the Dolan DNA Learning Center is unique, in that I get to interact with different children every day and teach them some of the most exciting science they probably will ever be exposed to. I have the opportunity to learn more practical science than I did in any of my molecular biology courses in college, as well as the taking advantage of all the resources at the Cold Spring Harbor Laboratory.

My mother teases that she hoped I would take this job, so I could find someone at the Lab to clone her precious dog Brandie. But that will probably never happen.

Valerie Meszaros

Administrative Manager,
Onsite Programs

I grew up on Long Island in Manhasset, lived for a while in Manhattan, and then moved to Huntington where I have lived for forty years. While earning a B.A. from SUNY New Paltz, I managed to do some traveling for which I developed a lifelong passion, enjoying the diversity of different cultures and natural environments.

Over time I worked for two major Manhattan law firms and on Long Island for a small firm handling radio advertising and a large telephonic communications corporation. I also spent some time working for a local newspaper where I learned some valuable skills in producing a publication. Subsequently I spent years editing, writing, and designing a series of self-healing books based on Taoist practices. Many of these books were translated into other languages and can be found in parts of Europe and Asia.

When not working, I facilitated groups for a mothers’ center, where I also published a newsletter and fundraised. I continued this type of rewarding endeavor for eleven years as a PTA board member where I enjoyed many friendships and learned many skills through years of interactions with children and their parents, teachers and administrators.

My husband is a retired concept design engineer who was born and raised in Hungary. As a young man, he played professional soccer for a Parisian team before moving to the United States. We have a son who attended the DNA Learning Center summer camps and introduced me to my future place of employment. He is a cellist and a world traveler who recently has found a career as an Urban Planner in a nearby township. He has many plans!

Cold Spring Harbor Laboratory is providing me with a wonderful working experience. With the DNA Learning Center as a large part of its educational outreach effort, our hardworking staff brings science education to children, teachers, and the general public. We interact with many middle schools, high schools, colleges and universities. Our reach is from Long Island, to across the United States, to many parts of the world. Some of our staff members originate from other countries. Working alongside them has provided me with more of the rich cultural education I have been interested in for so long.

My spare time is spent reading and writing, creating art, enjoying music, and hiking. My son and I have hiked many mountains including the Tour du Mont Blanc; it doesn’t get better than that.

Bruce Nash, Ph.D.

Assistant Director for Science

My first real memory is of me on a hike by the ocean; my second is of me taking a picture of a flower at my house. It seems that I was always out in nature looking at things or just soaking it in. Maybe soaking in it might be more accurate; I loved mud puddles as a kid! That, along with my dad being a science professor and my mom being a teacher, led me naturally to biology and I ended up studying how cells divide and develop into complex things like worms or people using genetics in the nematode Caenorhabditis elegans: I first studied genes that control how nerve cells grow to their targets as a graduate student at the University of Toronto and then moved to the University of Oregon to study how cells divide.

The longer I stayed in science, the more my interests switched from doing lab work to teaching. I found that I was most interested and satisfied when helping others learn. I looked for opportunities to lecture, enjoyed teaching lab members “worm” genetics and even became an active volunteer with educational groups, where I was a nature guide, taught school children biology experiments in school gardens, and taught teachers the use of school gardens as a living lab.

Perhaps most telling for me was the day I identified the lesion in the latest mutant I was studying: I had cloned another gene! Shouldn’t I be thrilled? I was happy, but I was much happier showing a third-grade student a bird’s nest on a nature hike and discussing with her why the bird on the nest was mottled brown. At that point I knew: I had to find a way to teach science. When I looked for a good place to teach biology, I found the DNA Learning Center. It just seemed right when I checked it out, and lucky for me they wanted to hire a “worm person”. I found a great place to teach cutting-edge science.

Now that I have been here for more than ten years, I have been lucky enough to work with a great team as we create new teaching programs on genetics, molecular biology, ecology, and bioinformatics. I’m especially proud that I have helped thousands of students do independent research using RNA interference or DNA sequence to study biodiversity. I have also been able to train educators in the region, around the country, and in far-flung places like China and Singapore.

It’s great—and I still get to go out in the wild to hike, bike, and sail and play with the creatures in nature, or collect invertebrates in mud flats with students.

I tossed the slides of insect parts that came with my brand new microscope, a Christmas gift from my parents when I was 8. I was determined to see an amoeba! Though my initial attempts proved unsuccessful with a toy microscope, I loved the idea of being able to study a world we couldn't see with the naked eye.

In high school, I became fascinated with the seemingly simplistic structure yet complex nature of DNA, which narrowed my focus to molecular biology. I graduated with a bachelor's degree in biology from SUNY Geneseo and pursued a Ph.D. in biochemistry at the University of Rochester School of Medicine and Dentistry, where I studied protein-DNA interactions and chromatin regulation. I continued my research there as a postdoctoral associate in the microbiology department, where I investigated the effects of post-translational modifications on the activity of DNA replication and repair proteins. During my time as a graduate student and postdoc, I had many opportunities to tutor, teach, and mentor students, as well as participate in a hands-on science education outreach program with students from surrounding elementary schools. I realized that I had a passion for teaching in addition to my love of laboratory bench science.  I was thrilled to discover the DNA Learning Center, whose interactive approach to science education for students reflected my own views and experiences, and knew that I had to be a part of the action!

By the way, I did eventually get to see my amoebas… and they did not disappoint!

I have been interested in insects for as long as I can remember. At a young age, I would have my mom read out of the Audubon Field Guide for Insects of North America while I fell asleep!  This interest persisted throughout my childhood and pushed me onto the path for a career in science, and I dreamt of becoming an entomologist. I lived my dream and went on to graduate from Cornell University’s School of Agriculture and Life Sciences in 2011 with a B.S. in Entomology, Plant Sciences, Neurobiology and Behavior, and Biological Statistics. Now, when I’m not teaching high school classes at the DNA Learning Center, I’m the Curator of Entomology at the Long Island Aquarium’s Butterfly Exhibit and Insect Zoo in Riverhead, NY where I get to work with exotic insects and spiders from around the world all day long!

During my undergraduate years, I discovered that I had a real interest in understanding how and why living things grow, behave, and change the way that they do. I became fascinated by how living things perceive the world around them, and how they use and respond to environmental cues through their physiology and biochemistry. In particular, I became interested how various animals perceive and use the Earth’s magnetic field for navigation. My research focused on how monarch butterflies use magnetic fields for navigation and how Drosophila fruit flies might process this information at the biochemical level. Eventually, I hope to revisit these topics one day and work on getting a Ph.D. in molecular biology or biochemistry.

While research is very important, I realized when I was very young that sharing what I learn is just as important and way more fun! When I was 12 years old, I began volunteering at Sweetbriar Nature Center’s butterfly exhibit in Smithtown, NY. It was here that I realized that not only am I captivated by the natural world, but I also enjoyed sharing that passion with others. I spent ten years at Sweetbriar teaching the public about butterflies, insects, and spiders. During that time, I also spent my school breaks and weekends volunteering for the American Museum of Natural History’s butterfly exhibit. Now, I share my passion with the guests at the Long Island Aquarium and have done so for more than seven years.

I got involved here at the DNA Learning Center in 2017 as a taxonomist, identifying insects, spiders and marine invertebrates for the Barcode Long Island Project. I remember my first experiences at the DNA Learning Center back in high school, and how much fun I had, but I never dreamt I’d be working here! As it turned out, an educator position had opened up, and I joined the team here at the DNA Learning Center as a High School Educator. I hope to continue to share my passion for science with every student that passes through our doors!

My academic life developed between the United States and my country of birth, Colombia. I went to high school in Colombia, where my biology and chemistry teacher inspired me to pursue a career in science. During high school, I read a few books on evolution. One of the books was “On the Origin of Species” by Charles Darwin. Although I didn’t understand all the concepts, Darwin’s theory of evolution by natural selection certainly intrigued me. Despite having a keen interest in evolution, as the first family member to pursue a college degree, I didn’t have much guidance. Based on the knowledge I had about scientific careers at the time, I decided to pursue a degree in pharmaceutical chemistry at the University of Antioquia in Colombia. I soon learned that pharmacy was not the right career path for me because it did not allow me to explore complex questions. What I did learn in pharmacy school was that I was interested in more integrated fields.

After four years as a pharmaceutical chemistry student, my family and I moved to New York. I enrolled as a biology major at Purchase College, where I learned to appreciate evolutionary biology as an exciting and complex interdisciplinary field. During my time at Purchase, I worked on the effects of climate change on different plant traits using the model organisms Arabidopsis thaliana. In my undergrad, I was also part of the MARC U-STAR program, where I had the opportunity to participate in an Amgen scholar summer fellowship at UC Berkeley. At Berkeley, I explored the role of the plant microbiome in the protection against plant pathogens. 

Thanks to the different research experiences, I have also discovered the art of teaching. Having the opportunity to explain concepts and ideas to peers and other faculty members encouraged me to continue learning how to communicate science effectively. What I enjoy about teaching is the challenge of breaking down complicated concepts into concise ideas. Although science is communicated mainly through the primary literature, I think it is necessary to communicate science to the general public. So, when I found out about the educator position at the DNA Learning Center, I was thrilled to join the team. Thanks to this opportunity, I will be able to motivate people through teaching and bringing the general public closer to science.

I was born and raised in New Jersey where I received my bachelor's degree in fine arts from Fairleigh Dickenson University. After graduating I worked a number of jobs in merchandising and marketing, most recently specializing in email marketing.

While in school I met my future husband, a DNA Learning Center field trip alum! Although Long Island is a stone’s throw away, I never stepped foot on the island until I was 21 and took a trip out to visit my future in-laws; I can truly say it was love at first visit. After finishing school I moved to Cold Spring Harbor and then to Long Island City. After getting married, my husband and I decided to move back to our favorite town, Huntington. We bought a 100-year-old house and it has been an adventure ever since.

It’s been a wonderful experience working at the DNA Learning Center. As a kid, science was always one of the most exciting classes for me, and being here today and witnessing the excitement of students as they experience the center is very rewarding.

My spare time is spent restoring my 1920s home (I now have a true appreciation for the people on HGTV), cooking (I’m working on it), traveling (at any point in time I have at least five dream trips planned) and refereeing my puppy Maddie and cat L’Orange (L’Orange always wins).

I don’t think I have ever read a biography, nor have I written one much more than the few sentences I hope to share with you here. Perhaps in the hundred or so pages of a book styled in this peculiar genre, may a reader gain some sense of understanding about the person’s life contained therein. My opinion has been that each person’s life, or at the very least my own, is such a dynamic evolution of chance and circumstance, that it is unwise to let history dictate outcome.

But philosophical quibbles aside, let me tell you at least a little about myself. Born and raised on Long Island, New York, I imagine I have found ideal surroundings for a “career” in science. I am not sure how I first got interested in science, but I had my own television when I was young, and without cable, PBS was the only channel I could get reception on. Hours of nature shows, broadcasts from the New York Philharmonic, and Julia Child, may have contributed to my interests (and modest talents) in science, classical music, and cooking.

My elementary/pre-school teacher still recalls me giving spontaneous science presentations to our small private school class. I also remember growing dismay at the shrinking size of the science aisle of the Toys “R” Us on trips with Mom to buy telescopes and chemistry sets. So, I guess science was destined to become my principle academic pursuit.

I enjoyed participating in various science projects and managed a win a few awards locally and nationally, and even had articles about my projects appear in various places, from the local school newsletter to the New York Times. All chance and circumstance I suppose, but maybe a clue as to what I should do. Graduating from the Half Hollow Hills School District, I attended the State University of New York at Stony Brook.

At Stony Brook I spent just about my total undergraduate course doing research in the university’s ecology and evolution department studying plant phylogenetics and systematics. I then had the good fortune to arrive at Cold Spring Harbor Laboratory, after graduating with a degree in Biology. At Cold Spring Harbor I worked with the molecular genetics of plant development in Arabidopsis. Another roll of the dice gave me the opportunity to also work in cancer research, looking into underlying molecular dynamics of prostate cancer.

Well, if you are willing to read this far, you might as well take the time to meet me personally at the Learning Center, because I would not want to bore anyone with more details. Perhaps I can leave you with these two comments

First, science tends to push its practitioners into very specialized modes of thought. Not that this empties people of their creative aspirations, but it has its benefits and costs. Now that stem cells (cells that retain the ability to become almost any other type of cell) are the subject of intense study in biology, maybe there is something to not being so quick to differentiate. Or put another way, maybe it’s not the destination but the journey.

Second, especially to any students reading this, be sure to be balanced and well read. Science is great, and its success is obvious. Still, science, just like any other human inquiry into knowledge, cannot hold a monopoly on truth. It is undeniably clear that you will need a basic understanding of science, to exist in the 21st century, let alone have a good chance at success. Still other areas of human existence, art, music, whatever your dreams are, have validity. Pursue your interests, understand science, but don’t let it become unexamined or unquestionable. Most of all, have fun!

Senior Multimedia Designer

It was my last year of elementary school, my mom signed me up for an art enrichment program admission exam at a junior high school outside our district in Taipei. I was admitted to the program and it was the beginning of my journey in art. I was then on track for continued art training in senior high school. Eventually, that led me to studying art at the university.

I always knew that I would go abroad to see other part of the world and after I graduated from college, I came to New York and to study computer graphics and multimedia. I then took a position at CSHL’s DNA Learning Center helping with web development and interactive media for its science education outreach mission. I didn't have science background and was not really interested in biology when I was in school. However, I am very fortunate to learn real science from the best educators at this world-renowned scientific institution, so I can create animations to help people understand science. I think that's pretty cool! I also have had the opportunity to meet and video interview many outstanding researchers, including Nobel Laureates, for our educational materials.

The DNALC is a very unique place to work, especially as a "multi" media designer. I started the job creating animations, but my tasks have extended from interactive media to desktop publishing and exhibition design. From photography, videography, online video, to live steaming media and webinar support. I also help plan and develop DNALC’s signature lab classrooms around the world, and assist with international collaborations. I am sure many other "multi" tasks await to explore, as we always try to be on top of what we do.

Manager of International Collaborations
High School Educator

After seven years of medical school training and three years working as a physician in China, in 1996 I followed my dream of moving to America to work in biomedical research and better understand health and disease. In 2000, I received my graduate degree in Biotechnology, with a major in Bioinformatics, from the Johns Hopkins University in Baltimore. That same year, I started a research position at Cold Spring Harbor Laboratory. The beautiful natural surroundings combined with cutting-edge science make this place heaven for me. My research results were published in 15 publications and I am the first author for five.

As a mother of two gifted children, I am very curious about the education system in the US and this curiosity brought me to the DNA Learning Center. The vision of Dave Micklos, Executive Director, about genetic education really fascinates me. I also believe science is not just for scientists. My position here at the DNA Learning Center as a manager of international collaborations and educator will enable me to share my passion, experience, and interests in science with different people, especially future scientists!
