I am a first-year Ph.D. student in the Janzen lab at ISU. During my B.S. studies in Wildlife Biology and Chemistry at Grand Valley State University, I examined the effects of climate warming on arctic tundra vegetation and, with Jennifer Moore, the population genetics of imperiled massasauga rattlesnakes (Sistrurus catenatus). I am interested in the evolutionary quantitative genetics - including the extent and role of plasticity - of key traits that underpin temperature-dependent sex determination in reptiles in light of rapidly changing environmental conditions.
