Harriet MacMillan, CM, a member of the Offord Centre for Child Studies, is a Professor in the Departments of Psychiatry and Behavioural Neurosciences, and Pediatrics at McMaster University with memberships in the Departments of Clinical Epidemiology and Biostatistics, and Psychology. Dr. MacMillan is the Chedoke Health Chair in Psychiatry, and is principal investigator of a five-year grant from the Centers for Disease Control and Prevention to study the development of an intervention to reduce intimate partner violence within the context of an existing home visitation program – the Nurse Family Partnership. Beginning in 1993 until 2004, Dr. MacMillan was the founding Director of the Child Advocacy and Assessment Program (CAAP) at McMaster Children’s Hospital, a multidisciplinary program committed to reducing the burden of suffering associated with family violence.

Dr. MacMillan’s research focuses on the epidemiology of family violence, including prevention of child maltreatment and intimate partner violence. She has led randomized controlled trials investigating the effectiveness of such approaches as universal screening in reducing intimate partner violence and nurse home visitation in preventing the recurrence of physical abuse and neglect among children.
