Animals live in rapidly changing and unpredictable environments. My research focuses on the behavioral and physiological changes that occur in response to unpredictable events (stressors), the hormonal and cellular mechanisms that underlie these changes, and the ecological repercussions of these changes for animals in their natural environment. I focus my studies on the adrenocortical response to stress, and the behavioral and cellular actions of glucocorticoids.
