She has worked on studies of both US and Canadian 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.
