Dr. Mariana Lazo’s current research interest involves understanding the contributions of socioeconomic and neighborhood conditions to the distribution of chronic liver diseases and risk factors (alcohol consumption and obesity), and to the observed disparities by race/ethnicity (particularly among Hispanics), by SES, and across and within cities in Latin American countries.

Dr. Lazo’s work has employed a broad scope of methodologies from primary data collection, to secondary data analyses of US national surveys and cohort studies, systematic reviews, and the conduct of clinical trials.

Dr. Lazo has conducted work in the U.S. but also internationally in Latin America.
