Stephen B. Thomas, PhD

Dr. Thomas is Professor of Health Services Administration and Director of the Maryland Center for Health Equity. One of the nation's leading scholars in the effort to eliminate racial and ethnic health disparities, Dr. 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. From 2011-2017, he was Principal Investigator (with S. Quinn) for the Center of Excellence in Race, Ethnicity and Health Disparities Research. Dr. Thomas has received numerous awards for his professional accomplishments. 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 affected and influenced the willingness of African Americans to participate in medical and public health research.

Mary A. Garza, PhD

Dr. Garza is an Assistant Professor in the Department of Behavioral and Community Health and Associate Director of the Maryland Center for Health Equity. Dr. Garza received her MPH from the School of Public Health at San Diego State University with an emphasis in health education and health promotion. Post MPH degree, Dr. Garza worked as a health coordinator for a federally qualified health center in Coachella Valley, CA where she gained valuable community-level experience working with low-income migrant farm workers (primarily Latinos and African Americans). She coordinated local, state, and federal community education and medical treatment programs with a focus on diabetes, cancer screening, hypertension, STDs, and HIV/AIDS. Dr. Garza returned to graduate school, and received her PhD in Health Policy and Management with a focus in Social and Behavioral Sciences from the Bloomberg School of Public Health, Johns Hopkins University where she also completed a post-doctoral fellowship in Cancer Epidemiology. Dr. Garza's research activities embrace the full spectrum of the intervention research process-from planning, developing, implementing, and evaluating, to dissemination of research findings - using a community-based participatory research approach. She has a strong interest in health disparities research, including understanding the interplay of psychosocial, behavioral, and neighborhood-level factors associated with health behavior; specifically, factors related to cancer screening. Dr. Garza's research interests also include the role and influence of religion and spirituality on health outcomes and domestic violence. Currently, Dr. Garza is the principal investigator of a NCI-funded, K01 Mentored Research Scientist Development Award to Promote Diversity (K01), titled “African Americans and Colorectal Cancer: A Multilevel Model to Assess Factors for Screening.” The objective of the K01 is to characterize individual and neighborhood-level risk and protective factors associated with colorectal cancer screening behavior among African-Americans. Additionally, Dr. Garza’s research involves assessing the prevailing perceptions, knowledge and attitudes toward participation in biomedical research, including clinical trials. Moreover, she is working with the Health Advocates in Reach and Research (HAIR) network, a barbershop initiative, to promote cancer screening in barbershops.
