UC Davis vs Penn State for biology: which is better for an undergraduate biology major?

UC Davis has the edge for an undergraduate biology major. Its biology ecosystem is unusually deep because the university is especially strong in life sciences tied to genetics, ecology, evolution, animal biology, plant biology, agriculture, and environmental science, and undergrads benefit from being in a campus culture where those fields are central rather than peripheral.

One concrete difference is the range of biology-adjacent resources built into Davis itself. The campus is closely connected to veterinary medicine, agricultural and environmental research, field stations, arboretum and natural reserve spaces, and labs that span molecular biology through whole-organism and ecosystem work. If your interests are broad or still shifting, Davis makes it easier to explore different versions of “biology” without needing to transfer into a different academic world.

Research access also tends to stand out at Davis because biology is such a major institutional priority there. Davis often feels more saturated with opportunities tied directly to biological research, including faculty work in genomics, microbiology, animal science, plant sciences, and ecology. For a student hoping to get involved beyond classes, that density matters.

The surrounding setting matters too. Davis is a college town with a strong science identity, and the campus culture is known for being collaborative, outdoorsy, and connected to environmental and agricultural issues in practical ways. Penn State has a very traditional Big Ten atmosphere and a strong alumni network, which some students love, but for biology specifically, UC Davis tends to offer a more distinctive undergraduate experience built around the field itself.

Penn State becomes more compelling if you strongly prefer its campus vibe, school spirit, or location, but on the biology question alone, UC Davis is the more impressive place to study it.
