David S. Fink

David FinkDavid Fink, MPH, MPhil is A SAETP pre-doctoral fellow and PhD candidate in Epidemiology at Mailman School of Public Health. He is interested in the influence of social arrangements and interactions on population health.  He is a social epidemiologist who has worked extensively with various branches of the military (i.e., US Army, Navy, Marine Corp, National Guard and Reserves) to investigate the psychological sequela of combat using a life course perspective.  His primary focus is on (i) the etiology of mental disorders, particularly substance use disorders; (ii) the extension of quantitative methods to estimate the health effects of policies and programs with a goal of (iii) improving population health through evidence-based policy.  He is the past president of the Society for Epidemiological Research Student Postdoc Committee.

Erik S. Jorgenson

Erik JorgensonErik S. Jorgenson, MPH, is a SAETP pre-doctoral fellow in the MSPH Department of Epidemiology. His research primarily focuses on the intersections of violence and health, and his current work involves investigating trends in adolescent opioid use to advance scientific understanding of the drugs-violence connection in American youth. A point of emphasis in his work is the use of “big data” in service of evidence-based policy and practice. His prior research leverages a range of national surveillance systems including vital statistics, crime reports, and survey data to answer fundamental questions about firearm use, injury offending and victimization, and youth and intimate partner homicide. His prior work includes countermeasures to reduce household injuries and minority health disparities in treatment access and utilization. Erik received a BS in Community Health from the University of Maryland, College Park, School of Public Health and a MPH from the University of Pennsylvania, Perelman School of Medicine.

Shadiya L. Moss

Shadiya MossShadiya L. Moss, MPH, is a SAETP pre-doctoral fellow in the MSPH Department of Epidemiology, where she was formerly an IMSD fellow. She is interested in substance abuse and psychiatric epidemiology, with a specific interest in marijuana use, depression, anxiety, and bipolar disorder among racial/ethnic minorities. Shadiya has worked as a researcher in the field of psychiatry for over seven years with the aim of improving the quality of life of individuals with mental illness. While at Columbia, she plans to expand on her prior research experience and focus on (1) improving the implementation and dissemination of interventions designed to treat substance use, mood, and anxiety disorders among racial/ethnic minorities and (2) reducing symptomatology in these populations by addressing the social, cultural and environmental factors impacting their treatment seeking behaviors and adherence to available treatment options. Shadiya is also interested in discovering novel ways to recruit and integrate racial/ethnic minorities into epidemiologic studies, in which they are consistently underrepresented. Prior to her doctoral training, she obtained a BA from Drexel University and a MPH from the University of Pennsylvania.

Alexander S. Perlmutter

Alexander PerlmutterAlexander S. Perlmutter, MPH, is a SAETP pre-doctoral fellow in the MSPH Department of Epidemiology. His research interests include methodological issues vis-à-vis addiction studies and the social determinants and consequences of addictive behaviors. He has worked with national data sets to measure relationships between prescription opioid use, employment, and age over time, how medical marijuana law enactments are related to knowledge of said laws, and how race modifies the relationship between marijuana use and arrest over time. He completed his MPH in the MSPH Department of Epidemiology in 2016. Alex has also worked in the Centre de Recherche d’Épidemiologie et Statistique Sorbonne Paris Cité, where he studied methodological problems in conducting health research. His projects there range from assessing primary outcome modifications in oncology clinical trials to evaluating the evidence base of mobile applications meant to curb substance use problems.

NICHOLAS VIVIO

Nicholas Vivio, MS, is a SAETP pre-doctoral fellow in the MSPH Department of Epidemiology. Nick is interested in comorbid psychiatric and substance use disorders, particularly among underserved populations both in the U.S. and Latin America. His interests range from the impact of substance abuse and depressive episodes on telomere length and the epigenome to developing new interventions that ameliorate quality of life among those with severe mental health and substance use disorders. In addition, he is keenly interested in the role that chronic stress and discrimination play in comorbid psychiatric and substance use outcomes (e.g. Latin American immigrants). Nick has a B.A. in Economics, M.S. Global Affairs, and a Post-Baccalaureate in Premedical Studies from Washington University in St. Louis. He spent several years working in the departments of neurosurgery and psychiatry at Washington University in St. Louis and nearly three years working as a Senior Research Coordinator in the Rehabilitation Robotics R&D Lab at the University of Pennsylvania. There he worked on the development of affordable, low-cost robotics for stroke survivors and children with cerebral palsy, both in the U.S. and in various LMICS.

Jose E. Diaz

José E. Diaz, PhD, is a SAETP post-doctoral research fellow in the MSPH Department of Epidemiology. He is interested in examining how larger social and political contexts (e.g., public health policies, neighborhood environments) contribute to sexual minority health disparities. In particular, he is interested in utilizing national data to deepening our understanding of the substance use disparities that exist among sexual minority populations. He completed his doctoral studies in sociomedical sciences with a concentration in psychology at Columbia University in February of 2018. His dissertation work explored how cultural (e.g., acculturation), neighborhood (e.g., ethnic density), and syndemic factors (e.g., substance use) contribute to HIV-related risk among Latino men who have sex with men (MSM). His dissertation work was nominated for the Marisa de Castro Benton Dissertation Award in Sociomedical Sciences for its outstanding contribution to the field. Prior to his doctoral training, Dr. Diaz taught high school English in Spain through a model United Nations curriculum focused on population health and inequalit
