- I am interested how hormones both constrain and enable birds (and other animals) to respond to their environment. The endocrine system integrates external and internal cues to orchestrate developmental, physiological and behavioral changes, but it is very sensitive to conditions during development. I am particularly interested in they ways in which conditions early in development permanently affect the endocrine system and therefore the behavior and physiology of birds.
