Research Interests

Our research lies at the interface of two topics: (1) the evolutionary dynamics associated with the divergent reproductive roles of males and females, and (2) the ecological factors that shape natural selection on physiology, morphology, and life history. Current projects in our lab are addressing causes and consequences of sexual conflict, the evolutionary and endocrine basis of sexual dimorphism, and the physiological and ecological mechanisms that shape life-history tradeoffs. All of these projects involve vertebrates (usually reptiles) and most combine both laboratory and field components, with an emphasis on experimental approaches and new genetic and genomic techniques. We conduct the field portions of these studies in diverse natural habitats ranging from the deserts and mountains of Arizona to coastal islands in the Bahamas and Florida. In any study, our overarching goal is to understand both how a particular phenomenon is regulated (physiology, genetics) and why it has evolved (ecology, evolution).
