Dr. William T. Tran MRT(T), MSc., PhD

Senior Research Fellow, Radiotherapy and Oncology


My research is to identify predictive and prognostic biomarkers in breast cancer. 

Specifically, I am interested in exploring quantitative imaging biomarkers from digital pathology and specimen-based markers to aid in treatment decisions for women with high-risk breast cancer. The primary endpoint of my research will be improved patient outcomes by using biomarker measurements for adaptive and response-guided cancer treatments.

Within this framework, my research is also focused on understanding treatment and survival outcomes associated with biological variances in early-stage invasive breast cancer. As part of a team of physician investigators and scientists, I am working alongside clinical experts to map the genetic and biological characteristics associated with chemotherapy resistance and radiation refractory breast cancer.
