I began my career in Pennsylvania with the U.S. Forest Service, U.S. Army Corps of Engineers, and U.S. Fish and Wildlife Service. In 1991, I transferred to a U.S. Geological Survey laboratory in Florida to help develop a geographic information system on invasive aquatic species. I have a Bachelors degree and a Masters degree both from The Pennsylvania State University.
