Research

​

We study the ecology, evolution, and physiology of wild animal populations, with a focus on lizards and other reptiles. Our projects typically involve long-term studies of natural and sexual selection in the wild, controlled breeding studies in the laboratory, and a variety of experimental approaches in both the lab and the field. Conceptually, much of our research asks how and why males and females evolve dramatically different phenotypes despite sharing the same genome. To answer this and other questions, we investigate the interactive roles of genes and hormones in facilitating and constraining adaptive evolution.
