Research Interests

I am an evolutionary biologist and Professor of Biology at the University of Montana. My research provides insights into the development and evolution of exaggerated male weaponry, such as the horns found in scarab beetles. I combine approaches from behavioral ecology, genetics, phylogenetics, and developmental biology to understand how evolution has shaped these bizarre structures. Current projects include an examination of how altered expression of appendage patterning genes contributes to species differences in the shape of horns, and how the insulin receptor (InR) pathway modulates the size of male weapons in response to the larval nutritional environment.  I also communicate the excitement of evolutionary biology to the popular press, such as National Public Radio and the New York Times, contributing to public understanding of animal diversity and morphological evolution.
