Research Interests


My research investigates the ecological and evolutionary processes that influence patterns of genetic variation among wild populations, and addresses fundamental questions about the evolutionary ecology of species in response to natural and human disturbance. My work provides crucial linkages between ecology and evolution, and is of increasing relevance to conservation, as the maintenance of evolutionary processes may promote ecological stability (e.g., via portfolio effects) and prevent extinction. My research in applied evolutionary ecology bridges the gap between academia and application and is used to advise conservation and resource management policy.
