Joanna Cohen is the Bloomberg Professor of Disease Prevention and the Director of the Institute for Global Tobacco Control at the Johns Hopkins Bloomberg School of Public Health. She also holds an appointment in the Dalla Lana School of Public Health at the University of Toronto.

Dr. Cohen obtained her PhD in Health Policy and Administration from the University of North Carolina - Chapel Hill and her MHSc in Community Health and Epidemiology from the University of Toronto. She has been involved in tobacco policy research for almost 20 years.

Trained in epidemiology and health policy, her research interests focus on the factors that affect the adoption and implementation of public health policies and on evaluating the beneficial effects and the unintended consequences of such policies. She has worked on studies of both Canadian and US legislators regarding tobacco and tobacco control policy, a longitudinal cohort of smokers focusing on factors influencing quitting behavior, tobacco promotion at the point of sale, tobacco prices including taxes, tobacco packaging, options for reducing the physical availability of tobacco products, and tobacco industry interference in tobacco control.

Dr. Cohen has been recognized for her teaching and mentoring, and has co-led a 6-year training program in public health policy.

She is a Senior Editor of Tobacco Control.
