Should I choose UCLA or Princeton for biology?

For biology, Princeton tends to fit the student who wants a smaller undergraduate-focused academic environment, very close faculty access, and a campus culture where independent research is built directly into the degree. UCLA tends to fit the student who wants a large, energetic public university with a huge biology ecosystem, broad course options, and access to major medical and research institutions in Los Angeles. Both can give you a strong biology education, but the day-to-day experience is meaningfully different.

Princeton is especially appealing if you like seminar-style learning, a tighter campus community, and the idea of being pushed toward original scholarship early. Its senior thesis requirement is a real plus for biology students who want a structured, substantial research project before graduation. Because Princeton is smaller and heavily undergraduate-centered, many students find it easier to build close relationships with professors and mentors, which can matter a lot for lab access and recommendation letters.

UCLA makes more sense for the student who wants scale and variety. Biology at UCLA sits inside a very large life sciences environment, so there are many subfields, labs, student organizations, and course pathways to explore. The connection to UCLA’s medical and research complex is a major advantage if you are interested in biomedical research, public health, neuroscience-adjacent work, or hospital-connected opportunities. You may need to be more proactive to navigate such a large institution, but students who are comfortable advocating for themselves often find a huge range of options.

For undergraduate research specifically, both schools offer real opportunities, but they feel different. At Princeton, research is often more intentionally woven into the undergraduate academic structure. At UCLA, the sheer volume of labs can be excellent, especially if your interests shift or become more specialized over time.
