I am interested in the taxonomy, phylogeny, reproductive biology, morphology, and evolution of invertebrate animals. The main focus of my research is the order Tanaidacea, a group of tiny aquatic crustaceans, with around 1400 species. However, past or ongoing collaborative projects in taxonomy and phylogeny have dealt with animal groups other than tanaidaceans, including isopods, amphipods, copepods, pycnogonids, nematodes, annelids, nemerteans, and xenoturbellids.
