Specific Interests

I am interested in animal behavior and the developmental, physiological, and social factors that can influence its expression. I and members of my lab primarily work with Anolis lizards to understand endocrine regulation of the development of sex differences, how stress physiology influences agonistic and reproductive behavior, and whether differences in stress responsiveness help to predict why some species are more successful invaders than others. Additionally, I enjoy collaborating on research projects with students and faculty colleagues at OSU and from around the country, as can be seen in the selected publications below.
