My projects focus broadly on how ecological interactions between species can drive the evolution of reproductive isolation and speciation. I study interactions between the specialist Sunflower Maggot Fly (genus Strauzia) and their host plant species (genus Helianthus and other Asteraceae). My primary project aims to evaluate the relative contributions of pre- and post-zygotic reproductive barriers to reproductive isolation between recently diverged lineages of Strauzia. This project carries the larger purpose of understanding patterns of ecological speciation across a continuum of divergence. In addition, I am working on several other projects that include completing a phylogeny of the genus Strauzia, measuring patterns of host plant use, and evaluating the evolutionary impacts of morphological differences between Strauzia species.
