Dr. Obasi has a current program of research that focuses on the neurobiology of stress, addictions, health disparities that disproportionately affect the African American community, and cultural predictors of health behaviors. As the director of the Hwemudua Addictions and Health Disparities Laboratory (HAHDL) at the University of Houston (UH) – a Biosafety Level II laboratory – he takes an interdisciplinary approach (incl., biomarkers, biofeedback, implicit cognitions, genetics, fMRI, experimental manipulations, etc.) and uses a diverse range of settings (incl., community, bar lounge, experimental rooms, medical facilities, etc.) to investigate biological, psychological, social, and cultural determinants of health. Dr. Obasi was an Early Career Mentee in the NIDA funded Transdisciplinary Center Focused on Rural African American Families (P30DA027827, PI: Brody) and recently completed a NIDA funded study entitled, Stress and Drug Use Vulnerability in Rural African Americans (R03DA027481, PI: Obasi). This study established a successful interdisciplinary research team that is committed to addressing health disparities and creating prevention programs that can have a positive impact on marginalized communities. Moreover, it provided strong preliminary data that supported Dr. Obasi’s current NIDA funded study entitled, Stress and Drug Use in the African American Community (R01DA034739, PI: Obasi). This project is one of the core qualifying R01s for the recently funded center of excellence: Vulnerability to Drug Use and HIV: Advancing Prevention for Rural African Americans (P30DA027827, PI: Brody) – where he serves on the Advisory Board, Pilot Core, and Inflammation / Neuroendocrine Core. Additionally, Dr. Obasi serves as MPI on a United Health Foundation grant that provides obesity and diabetes primary prevention services and intervention programs to Houston's Third Ward and East End communities. Dr. Obasi is the creator of two cultural assessment tools (i.e., Worldview Analysis Scale; Measurement of Acculturation Strategies for People of African Descent). He also has unique expertise in studying African / African American culture and mental health. This includes human laboratory studies, field data collections in African and African American communities, and large-scale longitudinal research designs.
Prospective Doctoral Students: Dr. Obasi is interested in mentoring students who would like to pursue a research career at a research intensive institution with a passion for investigating the effects of stress physiology, genetics, cultural worldview/practices, social environment, and/or drug use vulnerability on the development of health disparities. Ultimately, Dr. Obasi is committed to bringing about positive change to underserved and marginalized populations in the U.S. and beyond.
