Dr. O’Loughlin is a Professor in the School of Public Health at the University of Montreal School. She is also a member of the Carrefour de l’innovation et de l’évaluation en santé at the University of Montreal Hospital Research Center (CRCHUM), an elected member of the American Academy of Pediatrics Tobacco Consortium, a member of the Canadian Academy of Health Sciences and an invited member of the International Network for Research on Inequalities in Child Health (INRICH). She was a Tier 1 Canada Research Chair in the Early Determinants of Chronic Disease from 2004 to 2021. 

Her team is housed at the CRCHUM and in addition to local researchers Dr. O’Loughlin has ongoing collaborations nationally and internationally. Her research has focused on increased understanding of the relative importance of genetic, psychosocial, behavioral and environmental determinants of the childhood risk for adult chronic disease. She heads several longitudinal adolescent investigations (i.e., the Nicotine Dependence in Teens (NDIT) Study and AdoQuest) and she is a co-investigator on several others. Her research output includes over 360 publications and over 500 presentations at local, national and international conferences. 

A key indicator of how her work is influential, is its citation in “Preventing Tobacco Use Among Youth and Young Adults: A Report of the Surgeon General, 2012” and “A Report of the Surgeon General: How Tobacco Smoke Causes Disease: The Biology and Behavioral Basis for Smoking-Attributable Disease, 2010.” 

Her research is also cited in an INSPQ submission to the Quebec government on proposed legislative changes to the Quebec Tobacco Control Act. Overall Dr. O’Loughlin’s work exemplifies interdisciplinary research that is well-grounded in public health, it demonstrates leadership in child, adolescent and young adult research, and it provides the “cells to society” underpinnings for furthering early prevention of adult chronic disease.
