Fields: Invertebrate Zoology & Parasitology

My research focuses on the evolution and ecology of invertebrate animals. While my primary research interest is in the evolution and diversity of free-living nematodes, students in my lab also research other invertebrates, especially parasites.

Free-living marine nematodes —  Marine sediments support by far the greatest diversity of nematode species, and I aim to understand their diversity, evolution, and taxonomy.

Parasite ecology and evolution — My students and I study a variety of parasitic worms.  Examples include the diversity and distribution of leeches infecting turtles, the community of parasites in muskrats, and the attraction of a beetle host to a larval tapeworm.
