One of the nation's leading scholars in the effort to eliminate racial and ethnic health disparities, Dr. Stephen B. Thomas has applied his expertise to address a variety of conditions from which minorities generally face far poorer outcomes, including cardiovascular disease, diabetes, obesity and HIV/AIDS.  He is the Principal Investigator (with Dr. Quinn) on the Center of Excellence in Race, Ethnicity and Health Disparities Research, funded by the National Institute for Minority Health and Health Disparities (NIMHD).

Dr. Thomas has received numerous awards and for his professional accomplishments, and over the years, his work has become recognized as one of the scholarly contributions leading to the 1997 Presidential Apology to Survivors of the Syphilis Study Done at Tuskegee.  His current research focuses on the translation of evidence-based science on chronic disease into community-based interventions designed to eliminate racial and ethnic disparities in health and health care. More specifically, he has focused on understanding how social context shapes attitudes and behaviors of underserved, poorly served, and never-served segments of our society toward participation in health promotion and disease prevention activities. Dr. Thomas is particularly interested in how the legacy of the Syphilis Study at Tuskegee (1932–72) has impacted trust and influenced the willingness of African Americans to participate in medical and public health research.
