She holds the Heather Reisman Chair in Perinatal Research at Mount Sinai Hospital and is a senior scientist at the Lunenfeld-Tannenbaum Research Institute at Sinai Health. Previously, she held a Canada Research Chair in Perinatal Community Health at the University of Toronto. Professor Dennis has a simple maxim: “Healthy babies start with healthy parents.” This belief has led her to focus her research career on rigorously evaluating interventions that can directly improve the health of mothers and fathers, with the overall goal of improving child health and well-being. She has over 25 years of experience leading large cohort studies and clinical trials — including intervention care models that leverage technology to improve clinical effectiveness and accessibility — recruiting participants from all across Canada. She also developed the Breastfeeding Self-Efficacy Scale, the most widely used breastfeeding measure internationally, which has been translated into over 20 languages to identify women early who are at risk of poor breastfeeding outcomes. In total, Dr. Dennis has authored over 360 peer-reviewed research papers with an h-index >100 and has been involved in over 60 funded research grants, primarily focused on perinatal mental health. She has received numerous awards and honours and is the president-elect for the International Marce Society for Perinatal Mental Health.
