Clinical/Research Interests:

As a clinician with a strong interest in women’s oncological care, I primarily treat breast and gynecological malignancies. My main research goals include identifying and modulating biological predictors of radiation/chemotherapy response and in evaluating molecular basis of oncological outcome disparities in women’s cancers.

I am particularly interested in identifying and exploiting immunological mechanisms underlying radiation and chemotherapy resistance to achieve durable disease control in breast and cervical cancers. Additionally, I am interested in investigating the effectiveness of alternative radiation therapy modalities including neutron capture therapy, and whether novel functional imaging modalities could be used to identify tumor hypoxia and improve treatment response in difficult to treat malignancies.

Our lab has recently identified a M2 macrophage marker protein as a key mediator of radiation response in breast cancer. We believe its inhibition may overcome the commonly documented radiation resistance properties of triple negative breast cancer, and as such, we are currently working towards developing a clinical trial to further investigate this concept.
