Dr. Jillian Halladay

Clinical Epidemiologist & Registered Nurse

Through rigorous research, my mission is to work with youth and their loved ones to...

Understand co-occuring substance use & mental health concerns among youth
Develop & evaluate innovative prevention and early intervention initiatives
Support youth in living hopeful, happy, fun & meaningful lives

I am a Registered Nurse and Clinical Epidemiologist (Msc, PhD). My research is focused on deepening our understanding of the biological, psychological, and socio-contextual factors that contribute to co-occurring substance use and mental health concerns among youth (10-25 years of age), and how to prevent and treat this co-occurrence. I have clinical experience related to inpatient, emergency, and outpatient youth mental health and substance use. I have also supported the development and evaluation of several interventions for young people, including a new outpatient young adult substance use program in Hamilton (for those 17-25 years of age). My clinical and research roles are all grounded in identifying, contributing to, and utilizing the best available evidence to improve the lives of youth.

I am thrilled to be continuing my research as a postdoctoral fellow at the Matilda Centre for Research in Mental Health and Substance Use at the University of Sydney, Australia (remote until 2023). I am actively looking for career opportunities in Canada (ON or BC) to begin following my fellowship.
