I am an associate professor at the Society and Health Research Center at Universidad Mayor, Chile, an adjunct assistant professor of population health at the NYU Grossman School of Medicine, and an affiliated faculty at the Center for Opioid Epidemiology and Policy at NYU. My research focuses mainly on the epidemiology of substance use in Chile and abroad (e.g., Latin America, the US), including the analysis of its causes, consequences, and social determinants. I specialize on survey methodology, policy evaluation, and use of quasi-experimental methods in general. I have been the principal investigator of multiple studies to characterize and measure trends in substance use, treatment, and related problems in the Chilean population, including three waves of the National Drug Surveys among Secondary Students and two waves of the National Drug Survey in the General Population. I completed my PhD in Public Health at the University of Chile and a postdoctoral training at the University of California, Davis.
