Undergraduate Research Program

The Undergraduate Research Program (URP) at CSHL provides an opportunity for undergraduate scientists from around the world to conduct first-rate research. Students learn the scientific process, technical methods and theoretical principles, and communicate their discoveries to other scientists. Approximately 20 students come to CSHL each summer for the program, living and working in the exciting Laboratory environment.

URP participants work on an ongoing research project in one of CSHL’s expert labs. Research at CSHL focuses on:

  • Molecular Biology & Cancer
  • Genetics & Genomics
  • Neuroscience
  • Plant Biology
  • Quantitative Biology

In addition to doing research in the lab, URP participants attend a series of specially designed workshops, seminars and collegial events.  Workshops focus on learning particular skills, such as Python programming, while seminars cover research topics, responsible conduct of research, and career development. At the URP Symposium at the end of each summer, students present their research to the entire CSHL community.

URP participants live and work among CSHL scientists. They are invited to all Laboratory social activities, including an exclusive dinner with CSHL President Bruce Stillman. On weekends, students are free to explore nearby New York City or the sandy beaches of Long Island.

By the end of the summer, URP participants have first-hand experience of a career in scientific research.

The 2024 URP Program will be held Monday, June 10 – Saturday, August 10, 2024.

2024 Applications are now closed.

The Undergraduate Research Program (URP) at ư has been nothing short of transformative, both academically and personally. During the program, I was given the opportunity to work under the brilliant Dr. Adrian Krainer along with my two amazing mentors. The researchers and mentors are not only experts in their fields, but they also radiate a genuine passion for sharing knowledge and guiding aspiring scientists. I always felt welcomed and valued as a member of the Krainer lab, and the support I received was unparalleled. The mentorship I received was invaluable, and my mentors always took the time to understand my research goals and tailored their guidance to help me achieve them. The lab also promotes open discussions and collaborations while fostering an atmosphere of innovation and encouragement. One of the defining aspects of this program is the hands-on engagement with cutting edge research. My research project involved alternative splicing in pancreatic cancer, a very intriguing and stimulating topic.The Undergraduate Research Program not only advanced my technical and research proficiency, but also honed my critical thinking, problem solving and teamwork skills. There were plenty of workshops available such as the bioinformatics lecture series, python courses, and weekly talks from scientists from the Cold Spring Harbor Lab community. I am truly grateful to my inspiring lab and this transformative experience which has left an indelible mark on my academic journey, and I look forward to staying connected with this remarkable community as I continue to pursue my passion for research and academic career.

I did not know Cold Spring Harbor was what I needed until I knew. My experience here was quite unique from the group mentoring I received to how it has broadened the scope of my aspired career path. CSH offered me an opportunity to explore a field that I am quite passionate about (Medicinal Botany). At the college I currently attend there are no courses dedicated to this topic, so it was truly a privilege to be offered a position at CSH where I could immerse myself in the “plant culture.”The dynamics of my lab gave me a lot of independence, hence, I genuinely felt like I was able to get a taste of the Ph.D. experience. During the internship, I watched a Ph.D. student become a doctor, a post Doc move into her dream field, and a lab tech begin the next steps of her career. Sharing their experiences in and out of the lab, I received invaluable insight on three different career pathways post obtaining a Ph.D. Personally, my mentorship felt like a group project; everyone in the Pedmale lab contributed to dilating my skill-set in farm maintenance to wet-lab protocols and effectively presenting research. To be completely candid, harvesting seeds, infiltrating and imaging leaves easily became my comfort zone, oral presentation on the other hand … let’s just say whatever dessert was on the table went in my mouth before I got to the podium :/ By the time I had given my final presentation at the URP Symposium I was thoroughly pleased with how composed I was at the podium and the number of people who found my talk intelligible.

Everything was not perfect at CSH, but everything that happened here, I am beyond grateful for, and I would do it again in a heartbeat.

To Future URPs:

You’re going to make mistakes, and you’re definitely not going to know everything, but please, please apply if you’re interested. This internship is an amazing experience filled with lovely people. I’ve never interacted with more approachable directors than at this program; they care about your personal and scientific development and your entire experience in and out the lab. Believe me, CSH has made quite the impression, and I intend to be back. (Feel free to ask Kim or Monn for my email if you’d like to network 🙂)

P.S. Go sailing!

Being from a small town, I prefer smaller environments, so summer research in the Undergraduate Research Program (URP) at ư (CSHL) was perfect as the campus was small and world-renowned. I had a blast working in the Kinney Lab applying deep learning methods to quantitative biology research. Under the mentorship of Dr. Deborah Tenenbaum, I learned to overcome obstacles, improve my dry lab expertise and effectively communicate my scientific findings. It is an excellent program that prepares you for graduate school by training you to exercise critical thinking skills when faced with challenging research questions. Furthermore, I recommend future URPs take advantage of the small environment at CSHL by reaching out to faculty members whose research interests you. I am someone who has a myriad of scientific interests; therefore, it helped that the faculty at CSHL were willing to meet and answer my questions. Another excellent aspect of the program were the URP directors as they all cared to see us succeed and endlessly supported us throughout the entire program. With that said, I encourage prospective students to apply to the URP program as it is a high-quality program. To the next group of URPs, I hope you all enjoy the volleyball match against the faculty at the end of the summer, as it was my favorite memory since we almost secured the win without much practice!

This summer at ư has been very fruitful and productive! During the application period, I was taking Genetics at my home institution of University of Puerto Rico at Cayey. A lot of the history regarding the field was amazing, and once I got to the Grace Auditorium, it was then when I realized that I was in the same institution scientists revolutionized the field. My dream has been to study mechanisms of nutrition and metabolism since highschool, when I had lost 82 pounds. The URP Program fulfilled this dream by pairing me with Dr. Semir Beyaz, who works in nutritional factors, lipid metabolism and endometriosis. Alongside my mentors (Paul Bunk and Timothy Maher), and colleagues (Germaine Smart-Marshall and Sarah Shao) I was able learn and collaborate in a safe environment that valued my experiences as a researcher from Puerto Rico, working through the economic struggles, the pandemic and Hurricanes María and Fiona. I am so happy that I worked with them on the effects of fatty acid metabolism on anti-tumor immunity, and learned so many lessons from CSHL. Not only that, but I thoroughly enjoyed frisbee (organized by Leah Braviner) and Thursday Night Trivia! These experiences have set me to continue working in the field I desire most, where I can contribute significantly and help others learn about the importance of these factors in cancer.

I spent a truly memorable summer participating in the Undergraduate Research Program at CSHL, under the wonderful mentorship of Dr. Lingbo Zhang. I had the chance to use the revolutionary CRISPR-Cas9 technology and conduct targeted gene knockouts, which helped identify potential new drug targets for Leukemia. The intersection of genetics, bioinformatics, and therapeutics was captivating, and it enhanced my appreciation of biology research’s profound impact on clinical medicine. Through interpreting extensive data from public RNA-seq databases and working with the team to validate knockout efficiency, I learned about the precision and patience required in scientific investigations. This experience bolstered my confidence as a researcher and communicator, and affirmed my ambition to continue a career in scientific research.

Beyond the laboratory walls, life at CSHL was a memorable adventure. The camaraderie among the URPs was incredible. We shared many moments outside the lab—be it the late-night shows at James or exploring the vibrant life of the City—that forged lifelong bonds. The balance between rigorous scientific exploration and relaxing with peers enriched my summer, making it both intellectually and socially fulfilling. I strongly recommend this program to anyone passionate about scientific exploration, seeking a dynamic, enriching summer experience!

2022 and earlier Student Perspectives

Since 1959, the URP Program has been offering undergraduate students a unique opportunity to study with CSHL’s renowned scientists. Some of our notable alumni include Nobel laureate Dr. David Baltimore (California Institute of Technology), Dr. Gerry Rubin (HHMI, Janelia Farm Research Campus), Dr. Alfred Goldberg (Harvard Medical School), Dr. Geraldine Seydoux (Johns Hopkins), and Dr. Charles Gilbert (Rockefeller University), among many others.

NSF Sponsored REU in Bioinformatics and Computational Neuroscience

CSHL’s REU program in Bioinformatics and Computational Neuroscience was supported by the NSF 2005 – 2014 and 2016 – present.

The technological advances in this century open a new realm of biological questions that can be addressed experimentally. Large genomic sequence or image datasets are routinely and quickly acquired, but the resources and expertise to analyze this data present a challenge to researchers. CSHL’s unique NSF REU program in Bioinformatics and Computational Neuroscience addresses this need by providing early training to undergraduate students who might not otherwise pursue quantitative approaches. CSHL’s URP/REU students learn theory and techniques from an applied perspective, investigating an important biological problem rather than from the abstract perspective of computer science. Students are mentored by expert CSHL researchers, who combine biology, information theory and sophisticated computational techniques to address questions at the frontiers of modern genomics, bioinformatics, and neuroscience. In the past ten years, CSHL’s URP/REU program has recruited and trained a diverse group of students, many of whom are still working in bioinformatics or computational fields. Almost all URP/REU participants have continued in scientific careers and/or advanced degree programs at competitive institutions. The program provides students with a modern quantitative biology training program that aims to inspire young scientists to become active participants in modern biological research with its demands for quantitative and computational skills.
