My research focuses on understanding how the processes of natural and sexual selection shape physiological and morphological traits. Specifically, I am interested in how hormones link animals to their biotic and abiotic environments through the regulation of performance traits important to fitness. To accomplish this, I integrate theory and techniques from physiology, evolutionary ecology, animal behavior, and functional morphology, and I combine laboratory experiments with correlative studies of natural populations. I primarily work with reptiles as model systems, and I conduct research in the southwestern US and the Caribbean. Some of my current projects include:
- How steroid hormones mediate performance in lizards
- How endocrine systems regulate social behavior in Caribbean Anolis lizards
- Direct and indirect effects of sexually selected traits on animal performance
- Examining performance consequences of muscle fiber composition in lizards
