Erik S. Jorgenson
Erik 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.

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 whether and how larger social and political contexts (e.g., public health policies, neighborhood environments) and social identities (e.g., race/ethnicity, gender) play a role in sexual minority health disparities. He is particularly motivated to strengthen our understanding of substance use disparities that exist among sexual minority populations. For instance, his current projects examine racial/ethnic and gender-based differences in sexual minority substance use behaviors. He completed his Ph.D. 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 inequality.
