Research Interests

• Clinically relevant molecular and immune profiles of breast and colorectal tumors in AAs
• Heritable susceptibility to cancer among AAs
• Variability in estrogen receptor protein expression and racial disparities in ER+/HER2- breast cancer
 

Research Description

My research focuses on the impact of tumor biology and microenvironment on racial disparities in clinical outcomes for African Americans with cancer. Specifically, I have three main areas of active research: (1) Characterizing clinically relevant molecular and immune profiles of breast and colorectal tumors in AAs, (2) understanding heritable susceptibility to breast, prostate, and colorectal cancer among AAs, particularly characterizing variants of uncertain significance in known cancer susceptibility genes, and (3) understanding the role of variability in estrogen receptor protein expression in racial disparities in ER+/HER2- breast cancer survival and treatment with endocrine therapy. I am also interested in the combination of genetic factors and traditional epidemiologic risk factors, such as hormonal exposures and mammographic density, and how these may explain risk, biological changes in tumors, and ultimately survival. Much of my research utilizes data and biospecimens from the Detroit Research on Cancer Survivors (ROCS) cohort study, an NCI-funded prospective cohort study of African Americans recently diagnosed with breast, prostate, colorectal, and lung cancers.
