Amar Kishan, MD
Assistant Professor and Vice Chair, Clinical and Translational Research
Dr. Amar U. Kishan is an Assistant Professor in the Department of Radiation Oncology at the David Geffen School of Medicine at UCLA. Dr. Kishan graduated from the University of California, Berkeley with dual Bachelor of Arts degrees in Molecular and Cell Biology and Public Health. He earned his medical degree from Harvard Medical School, where he graduated magna cum laude from the joint Harvard-MIT Health Sciences and Technology Program. During medical school, he was awarded a Howard Hughes Medical Institute Fellowship to study tumor metabolism in the laboratory. He subsequently completed his internship training at Scripps Mercy Hospital in San Diego, where he was recognized as the H.H. Jones Intern of the Year. He then completed his residency training in radiation oncology at UCLA. He specializes in the utilization of radiation to treat genitourinary malignancies (particularly cancers of the prostate and bladder), as well as malignancies of the head and neck and central nervous system.
Associate 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.
Chair, UCLA Department of Radiation Oncology
Director, Clinical Affairs,
Dr. Michael Steinberg is Professor and Chair of the Department of Radiation Oncology at the David Geffen School of Medicine at UCLA. His professional career spans private, corporate and academic practice and is known for the development of multi-site radiation oncology care networks that are characterized by clinical excellence and community based clinical research. The UCLA Radiation Oncology network includes he department at Ronald Reagan Medical Center at UCLA, academically oriented community practices as well as Children's Hospital Los Angeles. Dr. Steinberg has specific expertise in the treatment of tumors of the GU system, breast and head and neck. He specializes in the use of technically advanced treatment modalities such as Stereotactic Body Radiation Therapy (SBRT) and brachytherapy for the treatment of malignancy.

Phillip Chow, M.S., DABR
Medical 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.
Chul Lee, M.S., DABR
Medical Physicist
Chul Lee has been working as a medical physicist at UCLA Radiation Oncology since January 2006. He obtained Master's degree in Medical Physics from Medical College of Ohio in December 2005. Prior to coming to UCLA, he worked as a researcher in radiochemistry laboratory for ten years at University of Michigan - Ann Arbor.
Steve Tenn, PhD, DABR
Associate 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.
