Assistant Professor
Bridget Keenan, MD, PhD is an Assistant Professor in the Department of Medicine at the University of California, San Francisco (UCSF) School of Medicine. She serves as Co-Director of the Cancer Immunotherapy Program and Medical Director of the Cancer Immunotherapy Clinic at UCSF. Dr. Keenan completed her MD and PhD at Johns Hopkins University School of Medicine in 2015, focusing on cancer vaccines to overcome immune suppression in pancreatic cancer mouse models. She completed her Internal Medicine residency at UCSF in 2017 and her Hematology/Oncology fellowship at UCSF with training in gastrointestinal oncology and cancer immunotherapy. In 2022, she completed UCSF's Diversity, Equity, and Inclusion Champion Training. Her research focuses on mechanisms of response and resistance to immunotherapy, particularly in gastrointestinal cancers. She clinically sees patients with solid tumor malignancies receiving cutting-edge immunotherapies including cell therapies and T cell engagers. Her work spans both basic science investigations of tumor microenvironment dynamics and clinical trials of novel immunotherapeutic approaches. Analysis of her recent publications (2023-2025) reveals a strong emphasis on gastrointestinal cancer immunotherapy, particularly CAR T-cell therapies for colorectal cancer, CD40 agonists for esophageal cancer, and mechanisms of immunotherapy resistance. She has significant contributions in biomarker development (including neutrophil-to-lymphocyte ratios) and has recently expanded her research to include gender equity in academic medicine. Co-Director, Cancer Immunotherapy Program Medical Director, Cancer Immunotherapy Clinic Principal Investigator on multiple phase I/II clinical trials for novel immunotherapies Active participant in UCSF's Diversity, Equity, and Inclusion initiatives Dr. Keenan's collaborative work spans numerous institutions and involves close partnerships with leading researchers in oncology, immunology, and bioinformatics. Her recent publications demonstrate growing leadership in both clinical immunotherapy trials and research addressing structural issues in academic medicine.
