My research interests lie at the interface of evolutionary biology and ecology (evolutionary ecology). For my PhD, I studied the factors creating within-species variation in body size and sexual size dimorphism of two species of seed-feeding beetles, Stator limbatus and Callosobruchus maculatus. In particular, I examined how both temperature and diet created variation in body size and sexual dimorphism through phenotypic plasticity (environmentally induced changes to the phenotype). The results of my research consistently show substantial variation in sexual size dimorphism within-species mediated by differences in phenotypic plasticity of body size between the sexes.
