Our lab explores major questions in evolution and quantitative genetics. We work with the nematode worm C. elegans and related Caenorhabditis species. Current projects include exploring how cryptic alleles in embryogenesis depend on genetic background, how development evolves over time, and the role of molecular mechanisms in trait determination and evolution. We are also interested in how the environment influences trait expression and imposes selection in natural populations, and are conducting field collection trips in the nearby Appalachian foothills. We are part of the School of Biological Sciences at Georgia Tech and the Southeast Center for Mathematics and Biology.
