Research Interests

Dr. Coffman is a physician scientist actively conducting laboratory based and translational research and maintaining a specialized clinical practice focused on the medical treatment of ovarian cancer. Dr. Coffman's research focuses on understanding and targeting the cancer supporting stromal tissues which are critical to the survival, growth and spread of ovarian cancer. Specifically, Dr, Coffman's lab studies a critical non-malignant component of the ovarian cancer microenvironment, the carcinoma-associated mesenchymal stem cell (CA-MSC). CA-MSCs are stromal progenitor cells which significantly increase cancer growth, enrich the cancer stem cell pool and increase chemotherapy resistance.

The lab studies how CA-MSCs are formed and develop tumor supporting properties. The lab also focuses on identifying important tumor cell:CA-MSC interactions which mediate CA-MSC's pro-tumorigenic functions and have potential for translation into new therapeutic targets. Additionally, the lab studies how CA-MSCs impact the development of ovarian cancer metastasis and the metastatic microenvironment.

The ultimate goal of this research is to translate novel laboratory findings into powerful therapeutic approaches for the prevention and treatment of ovarian cancer.
