Dr. David Cummings is a microbiologist with experience in microbial ecology, microbial physiology, and microbial genomics. At QERC, Dr. Cummings teaches the microbiology module of Tropical Ecology and Sustainability. At Point Loma Nazarene University, he teaches microbiology, Introductory Cell Biology and Biochemistry as well as Neotropical Ecology, which wraps up with a two-week excursion to the rain and cloud forests of Costa Rica. His research is focused on the ways bacteria can share genetic information, especially information that makes them less susceptible to antibiotics and better suited to cause disease. Dr. Cummings lives in San Diego with his wife Ann and their three teenagers, Sydney, Ryan, and Josh.
