Harriet MacMillan, MD, MSc, FRCP(C) is a psychiatrist and pediatrician with an MSc degree in Epidemiology and Biostatistics.  She holds cross-appointments as Professor in the Departments of Psychiatry & Behavioural Neurosciences, and Pediatrics and associate memberships in Clinical Epidemiology and Biostatistics, as well as Psychology at McMaster University.  Her areas of focus include the epidemiology of and interventions for child maltreatment and violence against women. She also conducts research in the area of Aboriginal health.   Dr. MacMillan has an established record in leading major research programs, and currently holds a Canadian Institutes of Health Research (CIHR) New Emerging Team (NET) Grant entitled “Health Impacts of Violence Across the Lifespan: A Multidisciplinary Approach.”   She held the Wyeth Canada CIHR Clinical Research Chair in Women’s Mental Health from July 1999 through to June 2004. Previously, she was supported by a William T. Grant Faculty Scholar Award. Along with Professor H. Thomas, Dr. MacMillan has completed a RCT examining the effectiveness of public health nurse home visitation in preventing the recurrence of child physical abuse and neglect. This trial involved collaboration with the Hamilton Department of Social and Public Health Services, as well as the child protection agencies in Hamilton, Ontario.  In addition to child maltreatment, violence against women was frequently identified within this study. As a result, both Dr. MacMillan and Professor Thomas have extensive experience in addressing the methodologic and ethical issues that arise in conducting a trial aimed at identifying family violence.  Dr. MacMillan was Director of the Child Advocacy and Assessment Program (CAAP) at McMaster Children’s Hospital between 1993 and 2004; she continues as an active member of CAAP. This program includes a multidisciplinary clinical team that provides assessment and consultation regarding family violence. As part of her work in this program, Dr. MacMillan provides assessment of female children and youth who are victims of acute sexual assault, and works closely with members of the Sexual Assault Domestic Violence Care Centre at Hamilton Health Sciences.
