Assistant Professor of Wildlife & Fisheries

Eric T. Hileman is an assistant professor in the Wildlife and Fisheries Resources program at WVU and serves as the quantitative ecologist for the Eastern Massasauga Rattlesnake Species Survival Plan. He holds B.S. and M.S. degrees from the University of Wisconsin‒Parkside and the University of Wisconsin‒Milwaukee, respectively, and earned his doctorate from Northern Illinois University. Prior to his current appointment, he was an assistant research professor in the Department of Wildlife, Fisheries and Aquaculture at Mississippi State University. Before this, he worked for nearly three years in the Brown Treesnake Laboratory in Yigo, Guam, as a Mendenhall Research Fellow for the USGS Fort Collins Science Center. Dr. Hileman’s research centers on population ecology. He uses a variety of sampling, methodological, and statistical methods such as capture-recapture and occupancy models to estimate population parameters and better understand the patterns and mechanisms regulating vital rates, population dynamics, and the distribution of species. Although he routinely studies snakes, he applies these approaches more generally to wildlife for inference in basic research and to inform conservation and wildlife management.
