Thomas O'Shea, PhD
Tom O'Shea is a Scientist Emeritus at the USGS Fort Collins Science Center.
Tom O'Shea has conducted research on bats, sirenians, and other mammals in the U.S., Africa, South and Central America, Asia, and Oceania. Dr. O'Shea is the author or co-author of about 140 scientific publications. He was formerly a researcher with the USGS, National Biological Service, and U.S. Fish and Wildlife Service. His current research emphasis is on bats (after a long hiatus in marine mammal studies and federal research management), particularly topics related to diseases, population biology, natural history, and environmental contaminants.
