Research Program
My research focuses on the ultimate processes that generate vertebrate diversity, including genetically or culturally transmitted
traits or those that arise through phenotypic plasticity. What environmental factors encourage plasticity in individuals? Shape the level of variation
within and among populations? Lead to isolation among gene pools? How does habitat alteration or climate change alter these processes?
