Evolution of development
Our research focuses on how genetic variation in translated through the developmental process into phenotypes, and how these phenotypes evolve. The importance of sequence changes that affect development to morphological evolution has been well established. But the phenotypic consequences of mutations that alter developmental regulators are often muted by the systems that buffer development against variation encountered in ontogeny. By studying the relationship between mutation and developmental phenotype, we gain insight into both the molecular forces that drive and constrain phenotypic evolution and the systems that keep development robust. To pursue these questions, we use a combination of genetic, genomic, computational, and imaging techniques, primarily in the model system of Drosophila.
