Justin earned a B.S. in Forest Resources from the University of Georgia and a Ph.D. in Biological Sciences from Florida International University. His research is broadly focused on conservation biology and the maintenance of biodiversity in human-altered landscapes. He has collaborated with undergraduates, graduate students, and senior researchers on work in the southeastern US and Costa Rica, with emphasis on amphibian assemblages. Of the processes that influence diversity, he is particularly interested in animal movement and factors that may determine rates of dispersal and gene flow in altered landscapes (e.g., migrant survival and individual behavior). For his dissertation work, Justin studied the influence of prevalent land uses on connectivity and diversity of amphibians in forest remnants in Sarapiquí, Costa Rica.
Justin’s work in the Todd lab is focused on spatial analyses of threats to Desert Tortoise populations and global-scale analyses of amphibian and reptile responses to anthropogenic pressures.
