Bio
Bio: Dr. Nadia Naomi Mbonde is an Implementation Specialist at CRESTNY, a medical anthropologist, mental health doula, and multimedia artist whose research centers Black reproductive mental health across the full reproductive lifespan—from menarche to menopause. She holds a Ph.D. in Sociocultural Anthropology from New York University, where she developed the concept of latency—how distress accumulates long before it's recognized as a crisis. She brings crisis response training skills from a range of settings, with expertise in perinatal mental health grounded in her training as a birth and postpartum doula, and peer support specialist for expecting and new mothers and families. She grew up globally, between East and Southern Africa, the Caribbean, and Europe, and is based in Brooklyn, New York.
