Bradford D. Hollingsworth, Ph.D., Curator

Bradford D. Hollingsworth with a Red-legged Frog

Brad has served as the department's curator since 2000, after previously serving as a postdoctoral fellow, guest curator of exhibits, expedition lead herpetologist, museum store employee, and volunteer. He completed his doctorate work from Loma Linda University, after receiving both his B.S. and M.S. from San Diego State University. His research focuses on the evolution and biogeography of the herpetofauna of Baja California and its associated islands, but also includes distribution analysis and thermoregulation (See research activities). Brad has served on the Editorial Boards and as an Associate Editor for various scientific journals, and currently is on the Board of Governors for the largest herpetological society, ASIH. He is an Adjunct Professor at San Diego State University and regularly teaches an introductory zoology course, The World of Animals. He has also taught a number of university courses in anatomy, histology, genetics, and molecular systematics. His major focus over the last few years is the implementation and completion of a whole-scale renovation of the Museum's amphibian and reptile collections.

J. Angelo Soto-Centeno, M.S., Collections Manager

Angelo Soto-Centeno capturing a Large-blotched Ensatina in the Sierra San Pedro Mártir, Baja California

Angelo has served as the department's Collection Manager since 2005. He earned his Master's of Science from University of Eastern Michigan in Ypsilanti and a B.S. from La Universidad Interamericana de Puerto Rico in his native country. Angelo started at the Museum in the Education Department in 2003. He also is an active participant on the Mammal Atlas project. Angelo has a broad range of zoological and collections care interests, but his specialty is bat biology.
