Welcome I have spent the past 20 years studying various aspects of amphibian and reptile ecology and conservation. Most of my work has dealt with snakes in general and rattlesnakes in particular. I try to bridge the gap between applied and basic research, using ecological, behavioral and natural history data to address conservation and management issues. I am an Assistant Research Scientist with the Desert Southwest Cooperative Ecosystem Studies Unit, an organization comprised of University, agency and NGO partners working together to address natural resource issues through science, education and technical support. I am the co-coordinator of the Southwest region of Partners in Amphibian and Reptile Conservation (PARC), a national organization dedicated to preserving our nation's herpetofauna. I also serve as science advisor to Partners in Parks, a non-profit organization whose goal is to support the National Park Service in their mission to protect natural resources.
