My research focuses on environmental control of reproduction and associated cycles of behavior, migration, molt, wintering strategies. We take a very integrated approach including theoretical and ecological aspects such as application of mathematical models to field data. While in the field we collect physiological samples from free-living animals, and experimentally manipulate phenotypes (through hormone implants) to tease out mechanisms of control.

 These data are then integrated with laboratory experiments under rigorously controlled conditions. Endocrine techniques are applied to samples collected both in the field and laboratory and investigations at the cell and molecular level are encouraged. Additional emphasis is emerging in the area of conservation biology and what field endocrinology can contribute to this more applied aspect of biology. My laboratory works primarily with birds, although all vertebrate groups are of interest.
