​Research interests

My research focuses on chronic disease prevention and global health in three main areas: tobacco/vaping, nutrition policy, and cannabis and harm reduction policy. In each of these areas, I lead large international studies to examine consumer trends and to evaluate the impact of national-level interventions, including restrictions on marketing, product standards, health warnings, and retail policies.
