Professional Focus

Dr. Steve Braunstein is a radiation oncologist with a clinical interest in the treatment of central nervous system, pediatric, thoracic, and soft tissue malignancies. He has expertise in modern radiation therapy techniques including stereotactic radiotherapy, intraoperative radiotherapy, and intensity modulated radiation therapy.

Dr. Braunstein earned his M.D. at New York University School of Medicine where he also obtained a Ph.D. studying essential molecular pathways by which cancer cells mediate response to radiation. Throughout his radiation oncology residency at UCSF, he has continued such work to further resolve genetic polymorphisms which yield the observed heterogeneity of tumor cell population radiosensitivity and risk of radiation-related secondary cancers. He continues to expand his work in current translational research efforts towards intensifying the tumor response while minimizing treatment-related toxicity for patients undergoing radiation therapy as part of modern multimodal cancer treatment.
