Research interests:

My research focuses on the developmental origins of suicide. I am interested in understanding how early-life experiences (i.e., occurring around birth, during childhood, and during adolescence) may influence risk of suicide later in life. I investigate these questions using longitudinal population-based datasets and a variety of approaches from psychiatric epidemiology, behavioral genetics, and developmental psychopathology traditions.
