SDSU / UC Riverside Evolutionary Joint Doctoral Program

As the organizing principle of biology, the study of Evolutionary Biology remains on the cutting edge of current biological studies and research. Students will receive training under the guidance and supervision of SDSU faculty who specialize in Evolutionary Biology, Ecology, and Molecular and Cell Biology, as well as participation from UC Riverside Faculty who specialize in Evolution, Ecology, and Organismal Biology. Students also take an academic year of residence at the UC Riverside campus, providing them with hands-on experience and expertise from faculty in various topics, including molecular evolution, genomics, paleontology, population biology, and systematics, reflecting the interdisciplinary nature of evolutionary biology.
