Undergraduate Program in Molecular Biology

Current Concentrators (Classes of '20 and '21)
Visit this page for important updates related to COVID-19, including revised deadlines for senior theses and junior papers.

Prospective Concentrators (Classes of '22 and '23)
Due to the COVID-19 pandemic, MOL courses taken in Spring 2020 with the P/D/F grading option will count as prerequisites provided the student gets a passing grade. Sophomores should visit this page for additional information about signing into Molecular Biology.


The undergraduate program in Molecular Biology is designed to provide students with the knowledge and skills they need to explore the central questions of 21st century biology. Our distinguished faculty are fully engaged in teaching and cutting-edge research on topics ranging from molecules to genomes. A cohesive core curriculum and a diversity of elective courses deliver a strong foundation in modern experimental biology. The capstone of a Princeton education is the senior thesis, when students consolidate their learning in a piece of original scholarship. In the Department of Molecular Biology, the senior thesis is a remarkable opportunity for students to work with world famous scientists, conducting independent research at the frontiers of modern science. Princeton's collegial and interactive environment also makes it easy for Molecular Biology students to pursue interdisciplinary interests, taking courses and working with faculty in chemistry, computer science, EEB, engineering, neuroscience, physics, and the Woodrow Wilson School. Upon graduation, Molecular Biology majors are poised to pursue a wide range of careers, including biomedical research, medicine, global health and policy, industry, education, and science writing.

The Molecular Biology Undergraduate web pages are designed to provide information to prospective students and current majors about the curriculum and degree requirementsresearch opportunities and independent workresources, and career activities.
