My research interests address both theoretical and applied questions in wildlife ecology and management. Within this framework, my research focuses on understanding the effects of habitat fragmentation and anthropogenic land use on the movement behavior, interspecific interactions, and population dynamics of vertebrates, the application of spatial data to elucidate resource selection and home range patterns, mesopredator ecology, the cascading effects of abundant mesopredators on local wildlife communities, the management of infectious diseases, and scavenging ecology.
