Our graduate program offers a master of science and doctor of philosophy degrees in four core areas, Molecular/Cellular Biology, Neuroscience, Ecology/Systematics, and Evolution/Genetics. The doctor of philosophy degree is offered through the University of Puerto Rico Intercampus Doctoral Program administered by us. The Department maintains close ties with the Medical Sciences Campus of the University of Puerto Rico, the Institute of Neurobiology, the Institute of Tropical Ecosystem Studies at UPR-RP, and the Department of Environmental Studies at UPR-RP, which expands considerably the opportunities for our graduate students. The Department has modern laboratory facilities and resources and uses traditional and non-traditional model organisms to address diverse questions. In addition, Puerto Rico’s enormous ecosystem diversity and easy access, translates into research opportunities in the Caribbean and the continental Neotropics. The University of Puerto Rico at Rio Piedras is a member of the Organization for Tropical Studies and students are encouraged to apply to the OTS courses.
