Profile

I began teaching at Shippensburg University in 1996. Prior to that, I moved around the western United States, earning my BS, MS, and PhD in New Mexico, Wyoming, and Arizona respectively. In between my MS and PhD studies, I spent six years teaching junior high and high school science and coaching track and cross country in northern New Mexico. Although I am interested in anything dealing with ecology or evolution, my real fascination is with the ecology of salamanders, turtles, and vernal ponds. I also have a strong interest in conservation biology, as human impacts threaten the future of the organisms and wild places that I cherish. My wife and I live on a small farm north of Shippensburg, where I spend much of my spare time enjoying the natural world and restoring native habitats.
