Mario is an applied microeconomist with research interests in the fields of health economics, labour economics and public economics.

He joined the Centre for Health Economics & Policy Innovation (CHEPI), based at the Department of Economics & Public Policy, as Research Associate in Economics (Taxation & Health). His current research focuses on how fiscal taxes can be redesigned to incentivise healthier consumption. Mario contributes to the Fiscal INCentives for Health improvement (FINCH) project funded by the National Institute for Health and Care Research (NIHR). The project looks at how consumption taxes on food can be repurposed to nudge people towards healthier choices. He is supervised by Prof. Franco Sassi (Director of CHEPI) and Dr Jack Olney.

Current research projects also include the health effects of economic shocks; the measurement of socioeconomic inequalities in health and healthcare utilisation; the effects of labour market reforms on fertility decisions; the viability of extremely preterm births; and public policy evaluation.

Prior to joining Imperial College Business School, Mario gained his PhD in Health Economics from Lancaster University funded by the NIHR School for Public Health Researchunder the supervision of Prof. Bruce Hollingsworth and Dr Eugenio Zucchelli. Mario also has a BSc in Economics from the Pompeu Fabra University (UPF), an MSc in Health Economics from the Erasmus University Rotterdam (EUR), and an MRes in Applied Economics from the Autonomous University of Barcelona (UAB).

He is also an External Affiliate of the Health Econometrics and Data Group (HEDG – University of York), and a member of the EvaluAES Committee at the Spanish Health Economics Association (AES).
