Biography
Dr. Chalfoun holds a BA degree in Biology from Smith College, an MS in Wildlife Biology and Conservation Biology from the University of Missouri, and a PhD in Wildlife Biology from the Montana CRU at the University of Montana. She joined the faculty at the University of Wyoming as a Research Scientist in 2008, and was hired as the Assistant Unit Leader for Wildlife at the Wyoming Unit in 2011. Dr. Chalfoun’s work has focused on understanding the mechanisms underlying habitat selection at multiple spatial scales, the contexts under which habitat choices are adaptive or maladative, nest predation dynamics, life history strategies including parental care behaviors, and the influence of anthropogenic habitat change on non-game wildlife. Dr. Chalfoun and her graduate students conduct research on songbirds, raptors, small mammals, and herpetofauna in a wide variety of habitats in Wyoming and beyond. The common threads woven throughout the lab's projects include wildlife-habitat relationships and the influence of human-induced habitat changes such as loss, fragmentation and degradation on sensitive species. Projects in the Chalfoun lab have included the effects of energy development, roads, and a changing climate. Dr. Chalfoun is the co-Chair of the Conservation Committee for the American Ornithological Society.
