生物学系于2009年扩展为细胞生物学，微生物学和分子生物学系（CMMB）和综合生物学系（IB）。每个系都有自己的主席和研究生主任，并向学生提供生物学理学硕士学位具有与CMMB或IB相关的特定浓度。没有一般的生物学MS专业。CMMB和IB部门位于设备齐全的现代建筑中。CMMB系的研究由跨学科科学大楼和生物科学设施大楼（BSF）的教员完成，而IB系内的大部分研究由位于科学中心大楼（SCA）的教员进行。由于大多数研究项目都是跨学科的，因此，教师和研究生经常在广泛的培训研究项目上共同努力，这些研究项目汇集了许多传
The Department of Biology was expanded into the Department of Cell Biology, Microbiology and Molecular Biology (CMMB) and the Department of Integrated Biology (IB) in 2009. Each Department has its own Chair and Graduate Director and offers students a Master of Science in Biology with a specific concentration associated with either CMMB or IB. There is no general Biology M.S. major. The CMMB and IB Departments are located in modern, well-equipped buildings. Research in the CMMB Department is done by faculty housed in the Interdisciplinary Science Building and the Bio-Science Facility building (BSF), and most of the research within the IB Department is conducted by faculty housed in the Science Center building (SCA). Because of the interdisciplinary aspect of most research projects, faculty and graduate students often work together on broad training research projects that bring together many of the traditionally separate areas of biology. Many of the faculty within CMMB and IB are involved in cooperative research with their colleagues in Chemistry, Public Health, Nursing, Medicine, Geology, Psychology, Geography, Marine Science, and Environmental Science. Often CMMB and IB graduate students have faculty members from these other areas of USF as members of their graduate committees.
