Research Summary

I am involved with the Urologic, Thoracic, Orthopedic and Gastrointestinal Oncology programs at UCSF. I spend 4 days per week providing clinical coverage for the above programs program. On average, I see 6 new patient consultations per week and 15 patients on treatment. I am responsible for patient simulations, treatment planning, supervision of external-beam radiation therapy, on-treatment visits, and follow-up visits. In addition, I am involved in the brachytherapy, intra-operative radiation therapy and stereotactic body radiotherapy programs. I attend tumor boards for GU, Thoracic, GI, orthopedic oncology programs and at the Veterans Administration Hospital. I work very closely with radiation oncology residents and medical students in all the above activities. I am the Director of the CyberKnife Radiosurgery Program at UCSF and proctor other faculty in this area. As Vice Chair of clinical services I over see clinical operations at the Mount Zion site, and over see the site directors at both the Parnassus Mission Bay and Washington Hospital.
