Dr. Diane Bridge is a Professor of Biology and Co-Chair of the Department of Biological & Environmental Sciences at Elizabethtown College, where she has been a faculty member since 2000. She completed her PhD at Yale University and conducted postdoctoral research at the American Museum of Natural History and the University of California at Irvine before joining Elizabethtown College.
Dr. Bridge's research focuses on the biology of aging using Hydra species as model organisms. Her work examines:
- Differences in lifespan between Hydra vulgaris (which shows negligible senescence) and Hydra oligactis (which experiences age-related decline)
- How stress response mechanisms, particularly heat shock response, explain differences in aging patterns
- Gene expression related to stem cell maintenance and longevity
- Roles of specific genes in protecting cells from stress-induced damage
Her research has revealed that H. oligactis is significantly more sensitive than H. vulgaris to heat stress and other environmental stressors, suggesting fundamental connections between stress response pathways and aging mechanisms. Dr. Bridge employs advanced molecular techniques including gene expression analysis, transgenic Hydra production, and cell type elimination in her investigations.
Dr. Bridge's research has been supported by significant grants from:
- National Institutes of Health
- Templeton Foundation
- National Science Foundation (previously)
As an educator, Dr. Bridge teaches courses including Invertebrate Zoology, Developmental Biology, and Principles of Ecology, Evolution, and Biodiversity. She actively involves undergraduate students in her research, with numerous student co-authors on her publications. The department's saltwater aquariums provide valuable resources for working with live marine invertebrates in both teaching and research contexts.
