Jeff is a member of the Eric N. Smith research lab enrolled in the Quantitative Biology PhD program at the University of Texas at Arlington. Jeff received an M.S. in systematic and evolutionary biology from George Mason University (GMU) in 2007. He also holds B.A. degrees in biology (2004) and theater (2003) from GMU. Research interests focus on the molecular biology and phylogenetic relationships of eleutherodactyline anurans (specifically the genus Craugastor), but also include physiological and ecological components. In addition to laboratory work, Jeff actively participates in field expeditions and has been fortunate enough to conduct biological work in Costa Rica, Mexico and the United States. When not in the lab, museum or field, Jeff enjoys making strange noises emanate from guitars. Obtained his Ph.D. in the Spring of 2012, with his dissertation entitled Evolutionary relationships in some northern groups of the direct-developing frog genus Craugastor (Anura: Craugastoridae). Jeff obtained an NSF fellowship for the East Asia and Pacific Summer Institutes for U.S. Graduate Students (EAPSI) to work in Singapore during the summer of this same year. In the Fall of 2012 he joins the laboratory of Dr. Matt Fujita (UTA) as a postdoctoral fellow.
