Overview
Students working toward the Ph.D. degree in Biological Sciences may pursue research in most of the major sub-disciplines. Our students produce internationally-recognized research, publishing in peer reviewed journals, and presenting at national and international meetings. In addition, courses provide a conceptual foundation and relevant and transferable experiences from grant proposal writing, to presentations, to networking. Students may design with advisors an individual plan of study or elect to pursue a sequence within the Ph.D. program in: Behavior, Ecology, Evolution & Systematics, Molecular and Cellular Biology, Neuroscience and Physiology.
