I am an evolutionary ecologist interested in understanding the origins of phenotypic diversity. My research aims to 1) connect evolutionary change with the underlying causal ecological mechanisms that generate selection and 2) link pattern and process across disparate timescales. In particular, I am interested in understanding evolution in lineages with separate sexes, a key feature of most metazoan populations. My research combines a variety of approaches including large scale ecological field experiments, evolutionary quantitative genetics in the lab, phylogenetic comparative methods, and in some cases the development of mathematical models. I work at the organismal level with taxa such as insects, amphibians, and fish.
