Dr Harriet MacMillan

Harriet MacMillan is a psychiatrist and pediatrician who has conducted family violence research for more than three decades. She retired in July 2024 from her position as a clinician-scientist at McMaster University and is now a Distinguished University Professor (Emerita) in the Departments of Psychiatry and Behavioural Neurosciences and of Pediatrics, and a member (Emerita) of the Offord Centre for Child Studies.
Harriet’s research has focused on the epidemiology of violence against children and women; she has led randomized controlled trials evaluating interventions to reduce child maltreatment, intimate partner violence, and associated mental health impairment. Harriet has worked closely with organizations such as the Public Health Agency of Canada and the World Health Organization (WHO). Examples of her work with WHO include co-chairing the Guideline Development Group (GDG) for the WHO Clinical Guidelines on Responding to Children and Adolescents who have been Sexually Abused, and the GDG for the WHO Clinical Guidelines on the Health Sector Response to Child Maltreatment.
From 1993 to 2004, Harriet was the founding Director of the Child Advocacy and Assessment Program (CAAP) at McMaster Children’s Hospital, a multidisciplinary team committed to reducing the burden of suffering associated with family violence. She saw patients as an active staff member of CAAP and provided consultations to child protection agencies until her retirement.
Harriet was appointed as a member of the Order of Canada in 2016.
