My research interests focus on the conservation and ecology of freshwater mussels, a group of benthic animals in which 70% of the North American species are considered threatened. Mussels are keystone species in many rivers and their catastrophic decline may lead to the decline of other faunal groups and the alteration of ecosystem processes. I use a combination of comparative and experimental approaches to understand factors affecting the distribution and abundance of freshwater mussels and to determine the roles that mussels may play in large river food webs. I also investigate the effects of sediment-associated contaminants on freshwater mussels.
