My research interests lie in two areas of Parasitology. First, I am interested in parasite-altered behavior of hosts. Parasites that require multiple hosts often employ strategies to increase the probability of transmission to their next host, including altering host behavior. I conduct lab experiments to study such questions using infected invertebrates. I also ask how chemicals such as fertilizers and heavy metals alter the normal behavior and growth of invertebrates.
Second, I am interested in using parasites as indicators of ecosystem health. Some parasites such as trematodes have complicated life cycles involving multiple hosts. Thus, the presence of the parasite in an ecosystem suggests the presence of its hosts. Since larval trematodes are easily and quickly collected from their snail intermediate hosts this research holds promise for a cheap and accurate way to assess ecosystems.
As a Jesuit priest, I'm interested in the intersection of faith and science. I'm particularly interested in the religious response to environmental issues. Some of my musings have been published on The Jesuit Post.
In the summer, I plan to take students to Pine Ridge Reservation in South Dakota to do biological field research.
