I am a clinical psychologist studying women's emotional, cognitive, and behavioral responses to changing hormones (estrogen, progesterone, testosterone) across the menstrual cycle. My primary outcomes of interest are suicidality, substance abuse, and interpersonal emotional symptoms (rejection sensitivity, shame, and anger/irritability).

Contrary to popular belief, the vast majority of women don't have serious changes in their feelings and behaviors across the menstrual cycle. However, about 6% of women do show severe emotional and behavioral symptoms around menses (DSM-5 Premenstrual Dysphoric Disorder). My research focuses on identifying who is at risk for this "psychiatric hormone sensitivity", and isolating the key biological and psychological variables that give rise to their symptoms.

I use a combination of double-blind hormone experiments and intensive naturalistic observation studies to understand how and for whom the menstrual cycle influences symptoms.
