About me

I am an applied economist interested in how people respond to policy and new technology, and how culture shapes the choices they make. Much of my work sits in healthcare, where I study systems financing and cost-sharing design, the elicitation of preferences and behaviours, and the political economy of health.

I am the Chief Investigator of the VaxPref project, a global initiative conducted across 22 countries and 14 Universities to explore preferences for vaccination campaigns and attitudes toward vaccination. I served as the Executive Guest Editor for the Special Issue 'Global Health Policies and Vaccination Strategies in The Endemic Phase', launched by Health Policy and Technology. You can read the Editorial here. 

Prior to my Ph.D., I worked in the Economic Advisory Team for the Chilean Ministry of Health.
