Biography

Like most in the field of fisheries science, I spent most of my free hours as a child fishing and enjoying the outdoors. I realized at a young age that I would like to find a career related to these interests, and have never been seriously interested in anything else. I graduated from Liberty University with a B.S. in Biology in 2007, and then a M.S. in Fisheries and Wildlife Sciences from Virginia Tech in 2010. I am now enjoying my research and ongoing education as a PhD candidate in the PA Fish and Wildlife Coop Unit.

Research Interests

I am interested in understanding the impacts of human activities on freshwater ecosystems and fish. Throughout my career I hope not only to elucidate some of the complex pathways by which these impacts occur, but also to provide useful guidance for mitigation activities to help conserve and protect these precious natural resources. I hope to spend most of my career involved in the many facets of water resources management and conservation in rapidly developing nations.

I am currently investigating the potential impacts that climate and land use change may have on stream habitat and brook trout populations in the Eastern U.S. throughout the next century. This project aims to offer predictions of stream habitat suitability for brook trout under different scenarios which will be useful for guiding conservation and management of this important species in a changing climate and landscape.
