Deanna Soper-Pinkelman received her Ph.D. from Indiana University in Ecology, Evolution, and Behavior and currently is a Visiting Research Scholar at the University of Iowa. Her research focuses on the effects of natural and sexual selection on the ecology and evolution of reproductive biology. Most of her work has been conducted using Potamopyrgus antipodarum, a freshwater snail from New Zealand. This snail has the unique feature of coexisting sexual and asexual reproductive modes and has a high infection rate by the sterilizing trematode, Microphallus livelyi. She has investigated how this naturally selective force has influenced the evolution of mating behavior, ploidy, and gametogenesis. In addition, she has also conducted research using the seed beetle Callosobruchus maculatus. This beetle is a cosmopolitan pest and females are known to mate multiply with males that have spiked genitalia. She has investigated how sexual selection through increased male density has altered mating behavior and the evolution of genital spike length. Deanna has also instructed courses at many institutions and has served as an undergraduate and graduate research mentor.
