Brief biography

Dr. Gerrish studies unique life histories in aquatic invertebrates in both marine and freshwater ecosystems. In freshwater, she uses long-lived dormant stages of crustaceans found in sediments to help reconstruct land-use change and aquatic food web changes over time. In marine systems, she studies bioluminescent ostracods that use lights for both defense and courtship displays. Her work focuses on how reproductive behaviors and habitat use influence rates and patterns of divergence.
