My research interests broadly focus on the influence that policies and environmental factors have on food choices and lifestyle behaviors and how these may be leveraged to create healthier nutrition environments and prevent obesity and chronic diseases. In my current research, I use qualitative and experimental methods to estimate the influence that food policies, like nutrition labels, have on consumer understanding and food selection. I use epidemiological methods to study associations between food consumption, particularly of ultra-processed foods, and chronic disease risk in nationally representative surveys in Colombia and in cohorts of adults and children in the US, the UK, and India. My Masters degree was at the University of Bristol (UK) where I studied Nutrition, Physical Activity and Public Health and my doctoral degree, in Public Health Nutrition and Obesity Epidemiology, was at the Harvard T. H. Chan School of Public Health (USA).
