I received my B.S. (major Zoology; minor in Chemistry) from the University of Rhode Island (1970) and my Ph.D. (Aquatic Ecology; Invertebrate Zoology) from Dartmouth College (1975). After graduate school I received postdoctoral training in Aquatic Ecology at the University of Washington (1975–77). My research focuses on rotifers, including their general biology, taxonomy, ecology, and dispersal. I am also involved in eutrophication studies of Wisconsin lakes. I have published >100 works, including research and review papers, book chapters, book reviews, laboratory manuals, study guides and test banks, as well as helping to edit four symposium volumes for Hydrobiologia. Ripon College has honored me seven times for teaching excellence (1981, 1982, 1993, 1996, 2001, 2006, and 2015).
