Dr. Dash’s research focuses on cancer epidemiology and prevention intervention studies among minorities and medically underserved populations. Some of his ongoing research projects include investigating the molecular epidemiology of oxidative stress among African-Americans, a pilot study of exercise among African-American men, and a study on the association of endocrine disruptors with breast density among women undergoing breast cancer screening. Dr. Dash is also part of transdisciplinary teams conducting research on physical activity interventions in high-risk health disparity populations, oral health disparities in the District of Columbia, and impact of environmental exposures on breast cancer.

Traci N. Bethea, MPA, Ph.D. is an Assistant Professor in the Office of Minority Health and Health Disparities Research and the Cancer Prevention and Control Program at Georgetown Lombardi Comprehensive Cancer Center. Her research focuses on chemical and non-chemical stressors underlying cancer health disparities affecting Black women with a particular focus on estrogen receptor negative breast cancer and ovarian cancer. Her current work continues research on breast cancer subtypes in African American women and also examines risk factors for ovarian cancer and for sleep disturbances. Her research on modifiable factors and breast cancer survivorship is supported by a career development award from the National Cancer Institute. New research directions involve the study of environmental and social factors as predictors of health disparities in cancer incidence and survivorship and aims to “bridge the gap” between the biologic, individual, and macroenvironmental levels. Dr. Bethea received a PhD in Environmental Health from Boston University School of Public Health and completed postdoctoral training in cancer epidemiology with the Black Women’s Health Study at the Slone Epidemiology Center at Boston University.

Kepher H. Makambi, Ph.D. (Associate Professor of Biostatistics) works in the Department of Biostatistics, Bioinformatics, and Biomathematics. He received his Ph.D. in statistics from the University of Dortmund (Germany). Dr. Makambi has many years of collaborative experience in the design and analysis of community intervention trials, behavioral studies, epidemiologic studies, basic science studies including proteomics and glycomics. His research interests include statistical methods in meta-analysis, adaptive design methods in clinical trials, structural equation modeling, statistical methods in epidemiology, and application of complex survey methods.

Collaborating Faculty

Alejandra de Mendoza, PhD (Research Instructor in the Cancer Prevention and Control Program) Dr. Hurtado is a bilingual Social Psychologist with training in Anthropology and Communication, Culture, and Technology. In the last ten years, she has conducted research on health disparities with underserved ethnically/racially diverse populations including Latinos and African Americans. Some of her ongoing research projects in translational genomics include the development of culturally adapted interventions to enhance the use of genetic counseling services in Latina women and Black women at-risk of hereditary breast and ovarian cancer. She is also developing a Social Network Research Registry to enhance the engagement of Latina breast cancer survivors in research. 

Tawara D. Goode, MA (Assistant Professor and Director of the Georgetown University National Center for Cultural Competence, Center for Child and Human Development)  Professor Goode is actively involved in the development and implementation of programs and initiatives in the area of cultural and linguistic competency at local, national, and international levels.  She had a primary role in developing curricula, assessment instruments, professional development series, and other resources that support cultural and linguistic competence in academic and clinical settings.  Her research projects and interests focus on the role of cultural and linguistic competence in addressing health and health care disparities and increasing the participation of underrepresented racial and, ethnic, and cultural groups in all aspects of research.  

Kristi D. Graves, Ph.D. (Behavioral Scientist) is an Associate Professor of Oncology and in the Cancer Prevention and Control Program at Lombardi Comprehensive Cancer Center. Dr. Graves received her Ph.D. in Clinical Psychology from Virginia Polytechnic Institute and State University and completed post-doctoral training at the University of Kentucky. Dr. Graves has led a PCORI-funded project to test an intervention that aims to help Latina breast cancer survivors and their caregivers improve their quality of life. Dr. Graves collaborated with Nueva Vida, Inc (Washington DC) and three other community organizations (two in New York and one in California) on this effort. Dr. Graves is also co-leading an R01-funded project to explore symptoms experienced by patients diagnosed with thyroid cancer who received radioactive iodine treatment. She is also leading a pilot study to understand the experience of stigma among African American, Latina and Chinese American breast and cervical cancer survivors. In prior work, Dr. Graves investigated ways to inform people about genetic testing for genetic changes related to small increases in cancer risk. She is interested in translational research and research that improves cancer survivorship.

Bridget Oppong, MD (Adjunct Assistant Professor of Oncology) Throughout her medical training, Dr. Oppong has maintained an interest in disparities research impacting women’s health, specifically in breast cancer outcomes, triple negative breast cancer and young women’s fertility after cancer diagnosis.
