She is also the co-director of the NIDA T32 Substance Abuse Epidemiology Training Program in the department ). She has co-authored >250 peer-reviewed epidemiological and substance use articles (>100 first or senior-authored), 90 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 and in 2021 the Columbia University Irving Medical Center Mentor of the Year Award. 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 cannabis laws in the U.S, the synergistic effects of opioid policies and cannabis policies on opioid-related harm outcomes in the U.S., the effects of opioid policies and substance use policies that target pregnant and postpartum women among women that use opioids in the U.S., and trends in drug overdoses in Latin America. She has been continuously funded by NIH since 2006 as a Principal Investigator.

Global Health 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.
Urban Health Activities
UNEMPLOYMENT INSURANCE AS AN INTERVENTION TO REDUCE DRUG-RELATED OUTCOMES AND DEATHS DURING THE COVID-19 PANDEMIC.: This project will produce scientific knowledge on the impact of structural causes, such as unemployment, as causes of drug and alcohol use disorder, which will lead to promote structural interventions to combat drug-related negative outcomes. This study will also help understand the importance of social safety net structures and evolving drug policy on health disparities, especially in the context of COVID-19.
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.
