She has co-authored >200 peer-reviewed epidemiological and substance use articles (>100 first or senior-authored), 80 of them led by her current or former mentees. She has served as PI or MPI of multiple NIH funded grants.Some of her notable research findings have focused on a typology of prescription drug monitoring programs and its impact on prescription opioid and heroin overdoses, machine learning techniques to better understand opioid policies associated with high-opioid prescribing, the effects of recreational cannabis laws in cannabis use outcomes in adolescents and adults in the US, and substance use and psychiatric disorders in child and adolescents in Brazil. She has received several awards for her research and mentoring, including, the 2017 Columbia University Mailman School of Public Health Dean's Award for Excellence in Mentoring. More recently, in 2021, she was selected as one of the School's 2021-2023 Tow Leadership Scholars and she received one of the 2021 Calderone Health Equity awards. Her current research focuses on consequences of medical and recreational marijuana laws in the U.S, recreational marijuana laws in Uruguay, prescription drug monitoring programs, the synergistic effects of opioid policies and marijuana policies on opioid-related harm outcomes, 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.

Select Global Activities

OVERDOSE DEATHS IN BRAZIL, COLOMBIA, MEXICO AND THE USA: A COMPARISON ANALYSIS, USA, Brazil, Colombia, Mexico: The overall aim of this proposal is to build capacity among researchers from Brazil, Colombia, and Mexico in the fields of epidemiology and psychiatry to analyze large datasets with secondary data available in each country in order to produce high-quality reports with information about drug overdoses and fill an important gap in the current knowledge. With that, we plan to better understand the drug scenario in the countries of interest and build up a solid background to shape specific public policies directed to high-risk populations.
The health and social consequences of national marijuana legalization : 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.
