Bradford D. Hollingsworth, Ph.D., Curator

Brad has served as the department’s curator since 2000, after serving as a postdoctoral fellow, guest curator of exhibits, expedition lead herpetologist, museum store employee, and volunteer. He received his doctorate from Loma Linda University and obtained both his M.S. and B.S. from San Diego State University. Brad’s research focuses on the evolution and biogeography of the herpetofauna of Baja California and its associated islands (see research activities). Brad is also an Adjunct Professor at San Diego State University where he regularly teaches a zoology course.

Melissa A. Stepek, M.S., Collection Project Manager

Melissa has served as the department's NSF Collections Project Manager since May 2008. She earned her M.S. in Biology from East Stroudsburg University and her B.A. in Anthropology from the University of California, San Diego. Melissa has over twelve years of wildlife and GIS field experience with a wide variety of agencies. She has a broad range of zoological and collection interests, but her main focus is herpetology. Her specialty is the behavioral ecology of freshwater semi-aquatic turtles.

Laura E. Williams, Collections Technician

Laura started at the museum in 2005 as a volunteer. In 2007, she was hired as the herpetology collections technician, working to renovate and care for the collection. She also works in the museum’s education department where she often travels to elementary schools to give talks about reptiles and amphibians. Currently, Laura is working toward her B.S. in Biology at San Diego State University focusing on animal behavior.
