Stereotactic Radiosurgery Experts at UCLA
Meet Our SRS Expert Team
The UCLA Department of Radiation Oncology, in conjunction with the Department of Neurosurgery, has been engaged in stereotactic irradiation for nearly 20 years.
Tania Kaprealian, MDAssociate Professor
Dr. Tania Kaprealian is an Assistant Professor in the Department of Radiation Oncology at the David Geffen School of Medicine at UCLA.
She completed her medical degree and residency training in Radiation Oncology at the University of California in San Francisco.
Subsequently she practiced at the American University of Beirut Medical Center where she was an Assistant Professor and Program Director in their Department of Radiation Oncology before joining the University of California Los Angeles (UCLA) Radiation Oncology Department. Dr. Kaprealian specializes in all treatments of all cancer types, but has extensive experience in in both Intensity-Modulated Radiotherapy (IMRT), stereotactic radiosurgery techniques, stereotactic body radiotherapy techniques, and other advanced techniques in radiation therapy.

Phillip Chow, M.S., DABRMedical Physicist
Phillip Chow graduated from UCLA with a Bachelor of Science degree in Physics in 1990. While attending graduate school in Astrophysics, he began working as a Medical Dosimetrist in 1992. He received his certification from the Medical Dosimetrist Certification Board (MDCB) in 1995. He then moved to Bangor, Maine in 1996 where he worked for two years as a Certified Medical Dosimetrist before being offered a position at Kaiser Permanente in Southern California. He stayed with Kaiser from 1998 to 2000 when he was accepted to the Biomedical Physics Graduate Program here at UCLA, starting in September of that year. He earned his Master of Science degree in Biomedical Physics in 2004 and shortly thereafter began working as a Medical Physicist here in the UCLA Department of Radiation Oncology. He is currently working on his PhD in Biomedical Physics while working full-time as a Medical Physicist at UCLA. More »

Prior to coming to UCLA, he worked as a researcher in radiochemistry laboratory for ten years at University of Michigan - Ann Arbor. More »
Steve Tenn, PhD, DABRAssistant Professor
Stephen Tenn joined the UCLA Department of Radiation Oncology in November of 2008. He received his PhD from the UCLA Biomedical Physics Graduate Program in 2007. His dissertation project focused on the accuracy of image guidance and gated radiotherapy using the Novalis Radiosurgery system. After completing his PhD Dr. Tenn left UCLA for a one year post doctoral fellowship at the Stanford University Department of Radiation Oncology. While at Stanford he worked with the CyberKnife radiosurgery team as well as with the Stanford Outreach physics program. Dr. Tenn's research interests include investigating image guided methods for accurate stereotactic radiosurgery/radiotherapy and stereotactic body radiotherapy treatments. More »
