My research centers on how proximate environmental parameters and physiological mechanisms are integrated at the neural level to control timing of seasonal reproduction in a variety of vertebates, primarily amphibians and reptiles. Recent research in my laboratory has extended to the effects of environmental endocrine disruptors on reproductive physiology and behavior. Additionally, I examine neuroanatomical and neuroendocrine correlates of different states on morphs of sexual behavior in males and females.

I think of my research as being multi-disciplinary and multi-level, combining both field and laboratory components. The following are projects underway in my laboratory:

Neuroendocrine control of reproduction in the big brown bat

The effects of relocation and burrow collapse on immunocompetence and stress responsiveness in the gopher tortoise
The effects of environmental endocrine disruptors in populations of amphibians and freshwater turtles
Patterns and effects of yolk hormone deposition in birds
Physiological effects of dietary carotenoid intake on birds with carotenoid-based plumage ornamentation
Sexual differentiation, hormones, and behavior in salamanders
Latitudinal differences in stress responsiveness in amphibians
Mechanisms of sex ratio adjustment in the zebra finch
