RESEARCH INTERESTS

    I am broadly interested in development and evolution of complex phenotypes. Because relationships among traits such as shared timing of development or common involvement in an organismal function patterns variation generated during development, these relationships can strongly influence the direction and potential of phenotypic evolution. However, despite their importance, we know little about how these relationships and their influence on developmental variation change through evolutionary time or across ecological contexts. My work integrates concepts and methods of development, morphological evolution, geometric morphometrics, and biomechanics to elucidate how developmental mechanisms ultimately generate interspecific diversity in animal form and function.
