Research interests
I am interested in systematics, conservation and evolution of invertebrates. Systematists are interested in discovering, describing and classifying the world's species. Such information is often critical for issues related to human health, medicines, agriculture and biological control, forestry, fisheries, conservation, and for our own edification. My students, collaborators, and I have been focusing a great deal of attention on freshwater mollusks, particularly unionid bivalves and pleurocerid gastropods and more recently terrestrial gastropods.
