David Cummings is a professor of biology at PLNU. As an environmental microbiologist, his research focuses on the interactions between anthropogenic pollutants and native bacteria in natural water, soil, and sediment habitats. In particular, he has been studying the presence of antibiotic-resistance genes in the Tijuana River Estuary and other Southern California waters. His research has gained both local and national media attention.
Cummings has an M.S. in zoology and a Ph.D. in microbiology, molecular biology, and biochemistry from the University of Idaho as well as a B.A. in English literature from PLNU. He was a post-doctoral fellow at the Idaho National Laboratory from 2000-2004 and joined the biology faculty at PLNU in 2004.
In addition to teaching on PLNU’s campus, he team-teaches “Neotropical Ecology” with Dr. Mooring every other spring, ending with a visit to the cloud and rain forests of Costa Rica. He also participates in Southern Nazarene University’s “Tropical Ecology and Sustainability” course in Costa Rica.
