Ph.D. in Biology, University of California, Riverside, 2007

B.S. Biology, University of North Carolina Wilmington (1999)

Dissertation Comittee Chair: Theodore Garland, Jr.

I am interested in the intersection of behavioral endocrinology with ecological and evolutionary physiology.  My dissertation research involves the Hypothalamic-Pituitary-Adrenal (HPA) axis of mice that have been selectively bred for high voluntary wheel running.  This study is aimed at providing insight into the processes by which the HPA axis can respond evolutionarily to changing physiological demands on an organism.  With support through the Center for Conservation Biology (CCB), I am also studying the effects of proximity to a major road on the HPA axis and reproductive success in desert iguanas (Dipsosaurus dorsalis), work that has implications for conservation biology.  This work is done in collaboration with Dr. Henry John-Alder.

In April of 2008, I will begin a postdoctoral position with Dr. Creagh W. Breuner at the University of Montana.
