Research Interests 

Peripheral hormones (e.g. glucocorticoids) and central ascending arousal systems (e.g. locus coeruleus efferents) contribute to cognitive/emotional processes that are critical for normal psychological functioning. These systems are also sensitive to stress, and under certain circumstances, may contribute to abnormal cognitive/emotional processes that result in psychiatric disorders. My research interests concern exploring how stress-induced changes in peripheral hormonal and ascending arousal systems contribute to abnormal cognitive/emotional processes.
