She is also the Department of Epidemiology Co-Investigator of the IMSD program at Columbia. She has co-authored more than 130 peer reviewed epidemiological and substance abuse journal articles, served as PI or MPI of multiple NIH funded grants. Notable recent findings have focused on recent trends in marijuana use, the relationship of perceived availability of marijuana with medical marijuana laws, traffic fatalities and medical marijuana laws and increasing trends in heroin use and heroin use disorder in the general U.S. adult population. She has received several awards for her research and mentoring, including, in 2011, the Award for pioneering efforts in gambling research, in 2013, the Columbia President’s Global Innovation Fund and more recently, in 2017, the Columbia University Mailman’s School of Public Health Dean’s Award for Excellence in Mentoring. Her current research focuses on consequences of medical marijuana laws in the U.S, recreational marijuana laws in Uruguay, prescription drug monitoring programs, social media and marijuana, and gambling and impulsive behaviors among minority adolescents in the U.S. She has been continuously funded by NIH since 2006 as a Principal Investigator.

Predictors of Impulsive Behaviors among Puerto-Rican Youth: This study integrates a developmental model of PG, Blaszczynski and Nower's Pathways model (so far only examined cross-sectionally) with a context -and intervention-informed developmental model of other risk behaviors (Ecodevelopmental theory). We will collect new information about gambling behaviors and PG on a high-risk population of 1,100 youth/young adults from two population-based samples of Puerto Rican (ages 15-26) from two sites: the South Bronx (SBx), NYC and San Juan, Puerto Rico (PR) by taking advantage of an ongoing study, the Boricua Youth Study (BYS-R01DA033172, PI: Duarte and R01MH09837, PIs: Alegria, Canino & Duarte), which has been following Puerto Rican individuals prospectively since 2001. This project is funded by the National Institutes of Health, National institute of Child and Human Development-1R01 HD060072.
Trauma, Mental Health, and Early Childhood Development: The overall aim of this proposal is to collect cross-sectional data among 1,250 4-6 year-old children attending preschool in Brazil and their caregivers. The goal is to identify potentially modifiable risk factors for the development of internalizing and externalizing psychopathology in early childhood, focusing on the central role of traumatic events experienced in early childhood among an urban population.
A natural history study of buprenorphine diversion, self-treatment, and engagement with formal treatment services: The overall purpose of this natural history study is to describe and analyze the nature and consequences of diverted buprenorphine use among heroin and/or non-medical pharmaceutical opioid users (NMPU) with DSM-5 opioid use disorder.

URBANICITY, CHILDHOOD TRAUMA AND ADOLESCENT COMORBID PSYCHOPATHOLOGY IN BRAZIL AND CHILE, Brazil, Chile: This project aims to build capacity among Brazilian epidemiology and child psychiatry researchers to conduct epidemiological longitudinal studies to identify potentially modifiable risk factors for the development of psychiatric co-morbidity (including substance use) from childhood to adolescence, focusing on the central role of traumatic events experienced in childhood among an urban population.
CITIES AND MENTAL HEALTH: EXAMINING SOCIAL DETERMINANTS OF MENTAL DISORDERS IN LARGE URBAN AREAS IN A MULTICENTRIC ANALYSIS OF THE WORLD MENTAL HEALTH SURVEY INITIATIVE, Brazil: This project aims to identify and analyze the social determinants of mental disorders in the ten megacities (cities with more than 10 million inhabitants) of the World Mental Health Survey Initiative (WMHSI): New York City, Los Angeles, Shanghai, Beijing, Shenzhen, Lagos, Mexico City, Paris, Buenos Aires and Sao Paulo, totaling around 20,000 individuals (an average of 2,000 per megacity), representing a reasonably well-distributed sample from low (Nigeria and China), medium (Brazil, Argentina and Mexico) and high (United States and France) income countries.
The health and social consequences of national marijuana legalization , Uruguay: To evaluate the impact of Uruguay's recent national marijuana legalization on adolescent and adult marijuana use and marijuana dependence, as well as on the consequences of marijuana use.
