During my academic and professional career, I have been involved in several research projects on a variety of wildlife conservation topics. This reflects my diverse research interests, including songbird ecology and conservation, habitat management and restoration, wildlife-habitat relationships, large mammal restoration, small population biology, and impacts of human disturbances on biodiversity. My research is best describe as applied. That is, my students synthesis their research findings into applied information that is used by various government agencies and conservation organizations to better manage and conserve wildlife and their habitats.
Prior to joining the IUP faculty, I was a research associate at the University of Kentucky and a visiting scholar at Yellowstone National Park. I have published extensively in professional journals and has contributed chapters to several books, as well as editing Large Mammal Restoration: Ecological and Sociological Challenges in the 21st Century, which won the 2002 Wildlife Society book award. My students and I have presented our research findings at numerous national and international symposia and conferences. I promotes active scholarship and applied research within the IUP Biology Department. I am a member of the Wildlife Society, the Society for Conservation Biology, the Cerulean Warbler Technical Committee, and the Golden-winged Warbler Working Group. Since 2013, I have been serving as the American Bird Conservancy's Forest Bird Habitat Coordinator. My primary role in this position is to work with conservation partners to implement science-based conservation in North, Central, and South America. I believe strongly that researchers should take an active role in converting their conservation science into conservation action!
Research projects that my students and I have recently finished or are actively working on include: 1) Estimating black bear population size in Kentucky; 2) Estimating fisher population size and distribution in Pennsylvania; 3) Cerulean Warbler response to forest management in the Daniel Boone National Forest, Kentucky; 4) Golden-winged Warbler breeding ecology and response to habitat management in Central Pennsylvania; 5) Identifying high-quality habitats of the Allegheny Woodrat within the Chestnut and Laurel Ridge systems of Pennsylvania; 6) Multi-scale resource selection of Pennsylvania elk; 6) Survival, movements, and habitat use of fledgling Golden-winged and Cerulean Warbler; 7) State-wide genetic atlas for Allegheny Woodrats and fisher in Pennsylvania; 8) Ecology and conservation of Honduran Emerald in the Agalta Valley, Honduras; 9) Use of wildlife overpasses by moose and roe deer in southwest Sweden; 10) Range-wide monitoring of American Woodcock, Golden-winged Warblers, and associated songbirds in response to young forest management on public and private lands.
