Bridget Keenan, MD, PhD

Dr. Bridget Keenan is an oncologist and physician-scientist, a doctor particularly focused on research. She cares for patients with solid organ tumors who are seeking or enrolled in immunotherapy clinical trials (studies of promising new treatments). She has a special interest in digestive system cancers.

Keenan's research investigates various immunotherapy approaches to fighting cancer, including checkpoint inhibitors (drugs that prevent an immune system response that may otherwise allow cancer cells to evade destruction), cellular therapies, bispecific antibodies (parts of lab-produced antibodies that bind to T cells and tumors so that cancer cells are directly targeted) and other new treatments.

Keenan earned her medical degree and a doctorate in immunology at the Johns Hopkins University School of Medicine. At UCSF, she completed a residency in internal medicine and a fellowship in hematology and oncology.
