 Profile

Dr. Jachowski is an Associate Professor of Wildlife Ecology at Clemson University in the Department of Forestry and Environmental Conservation. His passion for learning about and conserving wildlife has led him from the tropical rain forests of the Philippines (where he served as a visiting scientist and U.S. Peace Corps Volunteer), to the savannas of South Africa (where he remains an Honorary Research Fellow at the University of KwaZulu-Natal), and to the Great Plains of North America (where he spent 10 years as a federal wildlife biologist). In 2014 he moved to Clemson University where in addition to maintaining research collaborations in the Great Plains and Africa, a recent emphasis of his research is to investigate the ecology of wildlife in the Southeastern US.

 Research Interests

We live in a time of extreme biodiversity loss popularly known as the sixth mass extinction event. To mitigate future losses there is an urgent need to understand how remnant wildlife populations are adapting to global change. Taking the more optimistic glass half full perspective, there are opportunities for science to help advance the restoration of wildlife populations. Research by Dr. Jachowski and his research group falls along these two themes. Specifically, his research group is interested in studies that help better inform our understanding of (1) Restoration of Wildlife Populations, (2) Mammals in a Changing World, and (3) Human-Wildlife Coexistence.
