About Me

Welcome to my personal website. I am a health economist and environmental–lifestyle epidemiologist. I hold a PhD in Economics from the Catholic University of Argentina, and a second PhD in Health and Sport Sciences–Epidemiology and Public Health track from the University of Zaragoza (Spain).

I specialize in using tools from econometrics, epidemiology, and health data science to explore the complex relationships between physical activity, diet, and climate change and their impact on chronic diseases. I have extensive experience in causal inference using advanced statistical methods and have developed quantitative ex-ante evaluation models to estimate the economic costs and public health impacts (e.g., years of life lost, life expectancy) of unhealthy behaviors to provide evidence-based policy recommendations.

For over a decade, I have been conducting studies analyzing the health and economic burden of non-communicable diseases associated with physical inactivity, sedentary behavior, obesity, consumption of ultra-processed foods, pollution, and climate change, with a focus on low- and middle-income countries.
