Mathieu is conducting research on the topic of global legal epidemiology at the Global Strategy Lab, with an initial focus on the WHO Framework Convention on Tobacco Control’s effect on international tobacco consumption. He has a PhD from McMaster University’s Health Policy PhD program, where his research focused on applying innovative health equity metrics across national boundaries to uncover transnational gradients of health, as well as examining the impact of health policy on these socially and politically determined inequities. He has also conducted research on tobacco and alcohol tax policy, comparative welfare state studies, infectious disease and neglected tropical diseases, and healthcare system organization. He has an M.P.H. in global health practice from the University of South Florida, a B.S. from the University of North Carolina at Chapel Hill, and is Certified in Public Health by the NBPHE. He previously directed neglected tropical disease and vector-borne disease research for the Notre Dame Haiti Program from 2012 to 2014 in Léogâne, Haiti. Prior to that, he completed an internship with PAHO/WHO in La Paz, Bolivia concentrating on health equity analysis and health systems strengthening, and organized health promotion activities after the 2010 cholera epidemic in the Dominican Republic.
