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.

My work has received international media coverage in outlets such as The Washington Post, The Guardian, TIME, The Telegraph, ABC News, and The Mirror, as well as in leading medical publications such as The BMJ.
