I am interested in the general area of ecological and evolutionary physiology and endocrinology: the study of functional traits of organisms, their underlying (endocrine) regulation, and the significance of their variation in the natural world. I have investigated organismal energetics, thermal physiology, exercise performance capacities, and growth regulation, and I have included studies on thyroidal, gonadal, and adrenal endocrine systems. My general approach crosses traditional levels of biological organization from biochemical to behavioral and includes a blend of laboratory and field research. I stress the importance of field experiments solidly grounded in natural history. RESEARCH STATEMENT
