All Biological Sciences Majors must declare a concentration.

The concentration provides students with the opportunity to specialize in a particular biological discipline or, in the case of the General Biology concentration, take upper-level courses from multiple areas in biology.

The departments of Biological Statistics and Computational Biology, Ecology & Evolutionary Biology, Microbiology, Molecular Biology and Genetics, Neurobiology & Behavior, Plant Biology, and Biomedical Sciences participate in the major, as does the Division of Nutritional Sciences.

Concentrations are selected from the list below.
