About Angela R. Omilian


Dr. Omilian joined the Roswell Park faculty in 2019 and is currently an Assistant Professor of Oncology in the Department of Cancer Prevention and Control. She graduated from Cornell University and earned her PhD degree at Indiana University. Her main research focus is breast cancer disparities, particularly in regard to variation in immune subsets among different populations of women. She also uses evolutionary-genetic sequence analyses coupled with multispectral tissue staining approaches to evaluate the co-evolutionary dynamics between tumor and immune cells in breast cancer.
