My research has focused on phenotypic selection and evolution, particularly with regard to life history evolution in predatory-prey interactions. My primary model system has been the predaceous aquatic larvae of the dipteran Chaoborus americanus and the temporary-pond dwelling microcrustaceans Daphnia pulex and D. obtusa. I have worked on several questions involving patterns of quantitative genetic variation in Daphnia, and have developed a metric (Qst) that has become widely used in testing for the action of natural selection in leading to population differentiation. I have also worked extensively on predator-mediated inducible defenses in Daphnia.
