Sarah Boyle

Associate Professor of Biology, Chair of Environmental Studies and Sciences


Ecology, Conservation Biology, GIS & Remote Sensing

Dr. Boyle studies how human actions impact the distribution, ecology, and conservation of fauna and flora. Her research also addresses the extent to which a species modifies its behavior when living in areas of high disturbance. Dr. Boyle conducts research in Central and South America, as well as locally in Memphis. Current student projects involve behavioral research at the Memphis Zoo and the analysis of local forests using GIS.

Dr. Boyle also heads the Boyle Lab. Research in the Boyle Lab combines behavior, ecology, conservation biology, remote sensing and GIS in order to address how anthropogenic changes to the environment affect the distribution, persistence, ecology, and future viability of fauna and flora.
