Biology at Boston University is a broadly based department with faculty interested in biological problems at the molecular, organismal, and population levels, giving students the rare ability to address questions at all organizational levels of biology in ways that combine our knowledge in these areas. The undergraduate program leading to the BA combines a breadth of education with the opportunity to concentrate in one of these areas: Cell and Molecular Biology; Physiology, Endocrinology and Reproduction; Marine Biology; Neurobiology; and Ecology, Behavior and Evolution; or Quantitative Biology. Graduate program areas are Ecology, Behavior, and Evolution; Physiology, Endocrinology, and Reproduction; Neurobiology; Cell and Molecular Biology; and Marine Biology. Affiliated programs in Neuroscience; Marine Science, and Molecular Biology, Cell Biology, and Biochemistry also offer graduate degrees.
