Biology major

Biology: courses, careers, and where to study

Biology is the foundational pre-health major — covering molecular, cellular, organismal, and ecological levels of living systems.

A Biology major covers cellular and molecular biology, genetics, organismal biology, ecology, evolution, and physiology. Programs require a strong chemistry sequence (general and organic), physics, and calculus. Many BS-track programs require additional biochemistry and statistics. Common concentrations include Cell & Molecular, Ecology & Evolution, Marine, Microbiology, and Biotechnology.

Biology is the most common pre-medical major and a strong feeder into PhD programs in biological sciences. Graduates work in research labs, biotech, pharmaceutical, environmental, and clinical fields.
