Faculty Bio

Our research focuses on certain aspects of cancer progression and cancer treatment. These studies look at certain aspects of the micro-environment of tumor cells and how this may be altered to improve existing treatments, including chemotherapy and radiotherapy. We also are interested in the development of novel drug therapies for the treatment of cancer.
