CURRENT RESEARCH INTERESTS

 

African Americans endure a disproportionate burden of injury, disability, disease and death with regard to substance use. We are currently investigating novel mechanisms that can be leveraged to inform prevention and treatment efforts.

HEALTH DISPARITIES

SUBSTANCE USE
& ABUSE

Substance use is associated with negative behavioral outcomes (e.g., assault, injury, sexual violence, suicide), disease, and death. We are committed to finding real-world solutions to this preventable public health problem.

STRESS NEUROBIOLOGY

We are currently studying the cross-talk between cultural phenomena, chronic exposure to environmental stressors, and stress-related biomarkers to better understand psychological and behavioral outcomes in at-risk populations.

DR. OBASI'S HWEMUDUA ADDICTIONS & HEALTH DISPARITIES LABORATORY (HAHDL)

 

HAHDL

This laboratory consists of approximately 1,737 square feet of contiguous space that is divided into eleven complexes:

  1. simulated bar lounge experimental room,

  2. experimental computer laboratory,

  3. stress reception and preparation room,

  4. acute stress experimental facility,

  5. biosafety level-2 wet lab facility,

  6. biomarker storage room,

  7. experimental control room,

  8. data processing, analysis, and training facility,

  9. bar supply room,

  10. project coordinator office, and

  11. laboratory restroom.

 

The HAHDL is a sound-attenuated and temperature controlled experimental complex designed to leverage cutting-edge technology to discover new ways we can improve the quality and length of life for our local communities and beyond.
