stress, pregnancy and postpartum depression, biopsychology of stress, developmental psychobiology

I am interested in biopsychological processes in health and disease, specifically as they relate to human stress. My research focuses on (a) stress during pregnancy and its effects on postpartum depression, and (b) individual differences in stress reactivity (hormonal, immune, genetic).
