【Profile】

Thomas Rouyard is a Visiting Researcher at the Research Center for Health Policy and Economics (HIAS Health), Hitotsubashi University.

His primary research focus is on informing the development of evidence-based policies aimed at improving population health and mitigating health disparities. He holds a particular interest in leveraging insights from behavioral economics and related fields to design interventions that promote healthier choices and strengthen healthcare systems. His work encompasses the design and evaluation of such interventions, along with empirical investigations into health-related behaviors using diverse methods such as randomized controlled experiments, micro-econometric analysis of observational data, and evidence synthesis. Notably, a significant portion of his research projects is conducted in resource-limited settings, with a particular focus on West Africa. His recent work focuses on leading empirical investigations to guide policy development aimed at advancing universal health coverage and improving access to care among underserved populations in Francophone West Africa.

Thomas also serves as an Assistant Professor in the Department of Health Policy & Management at the CUNY Graduate School of Public Health & Health Policy. He earned an M.A. in Economics from the Paris School of Economics and a Ph.D. in Population Health from the University of Oxford.
