Assistant Professor
Department of Biology & Earth Science

Dr. Calinger-Yoak earned a Ph.D. from The Ohio State University in 2015 which focused on management strategies in wildlife populations. He uses veterinary, ecological, and computer modeling focused strategies to tackle complex problems. Through his experiences with agent-based modeling, he helped to create open-source projects that span the fields of veterinary medicine, ecology, mathematics, anthropology, and economics. In addition to academic research, he has taught many courses ranging from Introductory Biology to Human and Animal Physiology.
