Research Interests

My research interests focus on wildlife ecology and genetics, including studies of the genetic consequences of species reintroduction programs, the application of genetic tools for addressing issues in wildlife management, conservation, and disease ecology, the use of genetic markers to elucidate mating systems, movement behavior, and population structure of wildlife species, and sustainability of wildlife species in human-dominated landscapes with an emphasis on the resolution of human-wildlife conflicts.
