Dr. Laursen's research interests are snail/trematode interactions at the ecological and cellular levels. He is interested in the effects of trematode larvae on snails and the potential to use parasite assemblages as indicators of habitat quality (i.e. since trematode larvae harm their host snails, are snails which are subject to poor quality or polluted habitats more susceptible to trematode-induced pathology? And if so, are snails from high quality habitats better able to support more diverse and/or more numerous trematode infections?). He is also interested in larval trematode development, specifically using snail cell cultures to support larval trematode development and differentiation in vitro.
