Dr. Bradford Hollingsworth has had a life-long interest in the diversity of amphibians and reptiles. His research focuses on the systematics and biogeography of amphibians and reptiles of the Southwest, including the Baja California peninsula and its associated islands. He is responsible for the care and maintenance of Museum’s 78,000 amphibian and reptile research specimens and regularly teaches as an adjunct professor at San Diego State University. Additionally, Dr. Hollingsworth launched the Amphibian and Reptile Atlas of Peninsular California. The goal of the Atlas is to combine both Museum collection data and observations from citizen scientists to help better understand the biodiversity of our region. The Atlas is a binational effort spanning from southern California to the tip of Baja California. Dr. Hollingsworth is donating his author royalties to the San Diego Natural History Museum.
