Erin Kerrison, PhD

Postdoctoral Student
University of California, Berkley

My research explores the effect of state supervision on substance use and substance use disorders, violence, and other health outcomes for multi-marginalized ethnoracial minorities marked by criminal justice intervention. This agenda extends from a legal epidemiological framework, which foregrounds the ways in which law and legal institutions operate as social determinants of health. I maintain a strong commitment to expanding my conceptual, analytical, and research skills in the substantive area of substance abuse among Latinx underserved women who are criminal justice involved.

My research has been supported by the National Institutes of Health, the National Institute of Justice, the Ford Foundation and the Sunshine Lady Foundation. My recent empirical research has been published in Criminal Justice and Behavior, Women and Criminal Justice, the Journal of Developmental and Life Course Criminology and the Harvard Journal on Racial and Ethnic Justice. I hold a BA in Sociology and Philosophy from Haverford College, an MA in Criminology, Law and Society from Villanova University, and a PhD in Criminology from the University of Delaware. Prior to joining the faculty at UC Berkeley in the fall of 2016, I was awarded a Vice Provost’s Postdoctoral Fellowship at the University of Pennsylvania.

Manuel “Manny” A. Ocasio, MS

Doctoral Candidate, 4th Year
University of Miami

Manuel “Manny” A, Ocasio is a PhD candidate in the University of Miami epidemiology doctoral program and currently working on his NIDA F31-funded dissertation. His study uses a parallel strand mixed methods approach to examine the role of family in illicit drug use and sexual risk behavior in sexual minority Hispanic adolescent participants (SMHA) from the evidence-based, Hispanic-specific Familias Unidas intervention. The study aims to empirically test ecodevelopmental risk and protective factors in SMHA, evaluate the efficacy of Familias Unidas compared to prevention-as-usual among its SMHA participants, and qualitatively assess sexual orientation disclosure experiences of SMHA participants to their families. Synthesis of these results will provide key preliminary evidence for adapting Familias Unidas. The next phase will be to conduct formative research with SMHA and their families to adapt Familias Unidas and develop stand-alone, family-based intervention content that targets SMHA risk behaviors. He wishes to continue focusing his program of research on this vulnerable population subgroup and perhaps expand to young adult sexual minorities and other high-risk and understudied Hispanic populations, such as transgender youth.

Natalia A. Quijano-Cardé

Graduate Student, 2nd Year
University of Pennsylvania

Natalia A. Quijano Cardé is a PhD candidate of the Pharmacology graduate program at the University of Pennsylvania, Perelman School of Medicine (UPenn). Natalia was born and raised in Puerto Rico, and she received her BS degree in industrial biotechnology from the University of Puerto Rico, Mayagüez (UPRM) in 2015. As an undergraduate student, she was part of the Minority Access to Research Careers (MARC) program, which gave her the opportunity to participate in several research projects and network with outstanding researchers. During her time in the UPRM, Natalia conducted research in the chemistry and chemical engineering departments. Moreover, during the summer of 2014, she participated in the Summer Undergraduate Internship Program (SUIP) at UPenn and conducted research under the mentorship of Dr. Mariella De Biasi and Dr. Erika Perez on alcohol and nicotine co-abuse. In 2016, Natalia joined the De Biasi laboratory, where she investigates the efficacy of subunit-specific kainate receptor blockade to moderate alcohol consumption, and the mechanisms underlying such modulation. Natalia is particularly interested in advancing the identification of novel molecular targets for the development of more efficacious alcohol cessation aids that will particularly help the Hispanic population in the United States, which is disproportionately burdened by substance abuse disorders.

Diana M. Sheehan, MPH, PhD

Postdoctoral Fellow
Florida International University

Diana Sheehan is a postdoctoral research fellow in the Department of Epidemiology at the Robert Stempel College of Public Health and Social Work at Florida International University (FIU). Her research focuses on racial/ethnic and socioeconomic HIV disparities, particularly those that occur along the HIV/AIDS continuum of care, and those that occur among Latinos. In addition, much of her work has focused on the contribution of residential neighborhood to HIV disparities. As a predoctoral student, Diana was funded by the National Institute on Drug Abuse (NIDA) to conduct a study that examined disparities in delayed HIV diagnosis within Latinos of varying birth countries. Most recently, as a postdoctoral fellow, Diana was funded by the HIV Prevention Trials Network (HPTN) to conduct a study that examines perceived network sexual norms and HIV sexual risk behavior among drug users and their risk partners. As part of her research training, she completed a doctoral degree in epidemiology at FIU and a predoctoral health disparities fellowship at the Center for Substance Use and HIV/AIDS Research on Latinos in the US (CRUSADA). She also holds a Bachelor of Science and Master of Public Health degrees from Boston University

Vanessa Torres, MPH

Doctoral Candidate, 3rd Year
University of Washington

I am a third-year PhD student at the University of Washington, in the department of Health Services with an emphasis on Health Behavior and Social Determinants of Health. Currently, I am working as a Research Assistant under Dr. India Ornelas’ supervision and funded by a diversity supplement from the National Institute on Alcohol Abuse and Alcoholism (NIAAA). My research focuses on engaging Latinos in community based participatory research to gain a better understanding of the most effective and culturally appropriate intervention approaches that address substance abuse among Latino immigrant communities. In my dissertation, I am focusing on three papers on alcohol use and Latino immigrant men’s participation in research. I plan to continue working on my dissertation and incorporate substance abuse research as it relates to unhealthy alcohol use among Latino immigrant men. My research interests are to understand the complex ways in which gender, immigration status, poverty, and other contextual factors affect patterns of health behavior and health status in Latino communities. Previously, I earned my Masters in Public Health (MPH) in Health Promotion and Behavioral Science from San Diego State University in 2014. My career goal is to become a tenured faculty member at a research-focused university, with a faculty position. After completing my PhD, I plan to apply for post-doctoral research positions and then to a tenure track faculty position.
