My research interests fall primarily within the fields of evolutionary and comparative physiology. In general, my work has focused on asking two sorts of questions about physiologicalt raits: what sorts of patterns exist in populations or species for selection to act on, and what are the actual results of selection over many generations? To date, my work has focused primarily on whole-organism performance traits, examining the effects of hybridization and clonal reproduction on physiological performance in a sexual-asexual lizard genus, and the evolutionary effects of predation on escape ability in natural populations of guppies. More recently, I have begun looking at patterns of evolution in stressful environments by Escherichia coli, as part of a larger project headed by my PhD advisor Albert Bennett and Rich Lenski of Michigan State University.
