Department Overview


Founded in 2006, the Department of Radiation Medicine and Applied Sciences (RMAS) at the University of California San Diego (UCSD) is comprised of a large and diverse faculty of clinicians and researchers devoted to providing high-quality patient care, the development and adoption of novel radiation oncology technologies, and the advancement of academic radiation medicine through research, education and training.

Over the last decade, the Department has experienced unprecedented growth and is now the major provider of Radiation Oncology services in the greater San Diego region and has also become an internationally-recognized academic center. Below is an overview of the Department as a whole, including its faculty, treatment centers, research and educational programs. 


With the establishment of the UC San Diego Medical Center in the late 1960s, UC San Diego began offering Radiation Oncology services at its downtown location within the Hillcrest Medical Center.  Academically, Radiation Oncology was a small division of the Department of Radiology and at its peak included only 3 radiation oncologists.  It wasn't until the tenure of Dean Edward Holmes (2000-2006) that a decision was made to establish an independent Department of Radiation Oncology with the recruitment of Arno J. Mundt MD (right), an internationally-recognized academic radiation oncologist and educator, from the University of Chicago as the Founding Department Chair. 

From its humble beginnings in 2006, the Department has rapidly grown over the intervening years to include over 50 faculty, multiple treatment centers throughout the San Diego region and beyond, with a new patient volume exceeding 5000 patients annually, making UC San Diego one of the largest Radiation Oncology Departments in the Western United States.  Further growth is expected in the coming years with multiple new affiliations and centers outside of San Diego and abroad. In 2012, the Department officially changed its name to the Department of Radiation Medicine and Applied Sciences.  


Under the Chair, the Department leadership is comprised of: Casey Sandack MBA, Vice-Chair for Administration and Finance, and Todd Pawlicki PhD, Vice-Chair for Medical Physics. In 2016, an Advisory Board (RMAS Council) comprised of Vice-Chairs, Assistant Vice-Chairs (Cathryn Yashar MD, John Einck MD, Laura Cervino PhD, and Ajay Sandhu MD) along with elected junior faculty representatives was formed to provide additional and diverse input from the faculty as a whole. 

Academically, the Department consists of five divisions: Clinical Radiation Oncology (CRO), Clinical and Translational Research (CTR), Medical Physics and Technology (MPT), Proton Therapy and Particle Research (PTPR), and Veterinary Oncology (VO).  The individual faculty members in each Division are shown under People. The Academic Divisions are under the direction of the following Division Directors:

Under the Direction of Parag Sanghvi, MD, Associate Professor, the
Division of Clinical Radiation Oncology consists of the clinical radiation
oncologists at the main as well as the satellite sites.

Todd Pawlicki PhD FAAPM, Professor and Vice-Chair, was recruited as
Division Director in 2006 and oversees all clinical and research medical
physicists as well as technology researchers in the department. Several
division faculty members focus primarily on research and oversee post-doctoral
and graduate/undergraduate students.

Loren Mell MD, Associate Professor, was named Division Director in 2009 and
oversees the clinical translational and basic research in the department and
is the Director of the Center for Translational Radiation Medicine and Imaging.

Under the Direction of Carl Rossi MD, Professor, the Division of Proton
Therapy and Particle Research consists of the proton radiation oncologists
and medical physicists at the California Protons Cancer Therapy Center.

Dr. Gregory Ogilvie, Professor and Director of the Angel Care
Veterinary Hospital, serves as the director of the Division of Veterinary
Oncology which also includes Dr. David Proulx who is double-boarded
in Veterinary Medical Oncology and Radiation Oncology Oncology.


The RMAS Department consists of 5 treatment centers in San Diego including 4 photon therapy centers [La Jolla, Encinitas(Coastal North County), 4S Ranch(Inland North County) and South Bay] as well as a new state-of-the-art proton center (Mira Mesa).

The Department is in the process of establishing multiple new centers throughout the San Diego Region through joint ventures, partnerships and new constructions.  Affiliations and partnerships are also planned internationally.  In addition, through the RMAS Global Health Program, an affiliation has been established with the Institut Curie in Dakar Senegal, West Africa.

La Jolla (Main Center)
The La Jolla facility consists of administrative space, faculty offices, research and clinical space on the first floor of the Moores Cancer Center including a dedicated brachytherapy suite, wide bore CT simulator and 3Tesla MRI, as well as a conference center. Adjacent to the Cancer Center is a new 16,000 sq foot Department expansion consisting of additional clinical and administrative space including faculty offices, a PET/CT scanner and a dosimetry suite.  In La Jolla, there are 4 linear accelerators including 2 Varian True Beam units.

UC San Diego Radiation Oncology offers numerous cutting-edge clinical programs, many not available elsewhere in the region.  Several clinical programs are highlighted below:

The stereotactic radiosurgery (SRS) program at UC San Diego;is a joint program between Radiation Oncology and Neurosurgery. Initially using a customized bite-block and infrared-based localization, Department physicians have tremendous experience with frameless SRS in patients with malignant and benign CNS tumors and staff two multidisciplinary clinic with UC San Diego and Kaiser Neurosurgeons.

SRS cone pic.png

Attention has recently turned to the development of a novel frameless bite block-less SRS approach using 3-D surface video cameras.

Dr. Catheryn Yashar, Chief of the Breast Oncology Service, and Medical Physicist Daniel Scanderbeg PhD, were pioneers in the treatment of early stage breast cancer patients using the novel brachytherapy SAVI device.

Another tumor frequently treated with brachytherapy at UC San Diego is prostate cancer.  In 2009, Dr. John Einck, Chief of the Prostate Brachytherapy Service, was recruited to develop a new prostate brachytherapy program together with medical physicist Dan Scandebeg PhD. Patients with early stage disease are treated with LDR brachytherapy and high risk patients undergo HDR brachytherapy in conjunction with external beam irradiation.

Xoft pic.png
The opening of the expanded South Bay facility in 2015 added considerable capacity to the Xoft electronic brachytherapy skin cancer treatment program in South Bay. Currently, over 1200 electronic brachytherapy treatments are delivered annually at that facility. Expansion of the program to include gynecologic cancer is plannedfor the coming year.

UC San Diego physicians have a long history and experience applying novel radiation approaches in gynecologic cancers. Dr. Arno Mundt pioneered the use of IMRT in gynecology patients over a decade ago. In a series of outcome series, he demonstrated that IMRT was highly effective at reducing the risk of long term side effects in these women.

Dr. Catheryn Yashar, Chief of the Gynecologic Oncology Service, and Dr. Loren Mell, Director of the Division of Clinical and Translational Research have built on this experience by incorporating novel imaging techniques for treatment planning and in-room imaging for optimizing treatment delivery. Drs. Mundt, Yashar and Mell are frequent invited lecturers on novel radiation technologies in cervical cancer and other gynecologic tumors at national and international symposia and conferences.  In addition, both Drs. Yashar and Mell serve on the editorial board of the International Journal of Radiation Oncology, Biology and Physics. The former Senior Gynecologic Oncology Editor at the Red Journal, Dr. Arno J. Mundt is the Co-Section Editor for Gynecologic Oncology for the on-line resource Up-to-Date.

In addition, the Department provides annual support for research recruitment packages, totaling $375K in 2015.

Department Research is divided into 5 main areas: Outcomes Research, Technology Research, Imaging Research, Basic Science Research, and Clinical Trials Research.  Several of the Department Researchers and their programs are highlighted below.

Mell Lab
Dr. Mell.pngLoren Mell MD is an Associate Professor and Director of the Division of Clinical and Translational Research and the Director of the Center for Translational Medicine and Imaging. His primary focus has been on the development and application of novel radiation approaches in patients with cervical cancer and other malignancies. He is the founder and Principal Investigator of an international radiation cooperative group focused on the use of advanced technologies in women with cervical cancer, with members throughout the United States and in 25 foreign countries.

Bone Marrow Pic.png

Dr. Mell has developed novel planning approaches to reduce bone marrow toxicity in patients receiving chemoradiotherapy, a major barrier to increasing treatment intensity. An ASCO Young Investigator Award recipient, Dr. Mell has developed statistically-based approaches to identify critical BM areas which can be spared during treatment. He has also investigated, together with Graeme Bydder MD (Radiology), novel imaging approaches to characterize BM sub-regions, many of which were developed here at UC San Diego.

Murphy Lab
Dr. J Murphy.pngPatient Centered Outcomes.png
Associate Professor Dr. Jim Murphy's research interests revolve around improving healthcare delivery in radiation oncology, with a focus on three areas: eliminating treatment disparity, reducing cost, and increasing quality of care.  With treatment disparity he has partnered with Elena Martinez on a large-scale epidemiology project in metastatic colorectal cancer where they have discovered that racial differences in referral patterns and subsequent treatment account for a substantial portion of the inferior survival that minority patients experience.  This study will help identify barriers that once tackled will reduce racial disparity and improve outcomes and was accepted for publication in the prestigious Journal of the National Cancer Institute (JNCI).  

Breast Cancer Recurrance graph.png

With cost, ongoing research will help define the magnitude and impact of patient out-of-pocket cost for health care in patients receiving radiation therapy.  This research will quantify this potentially substantial underreported burden for cancer patients. Dr. Murphy is a recent recipient of several research grants including a K Award from the Clinical Translational Research Institute, a Young Investigator Award from the NCCN and Grants from the Radiologic Society of North America (RSNA) and the American Society for Clinical Oncology (ASCO).

Simpson Lab
Dr. Simpson.pngDr. Simpson is an Assistant Professor and his research is focused on the use of non-invasive bioimaging markers in oncology and incorporation of novel imaging modalities into radiation treatment planning. His primary research project is designed to evaluate the diagnostic accuracy of restricted spectrum imaging (RSI), a novel MRI diffusion technique, for pre-surgical assessment of treatment response in patients undergoing neoadjuvant radiation therapy for rectal cancer (see below). RSI offers several advantages over other radiographic modalities traditionally used in rectal cancer including improved tumor conspicuity and improved specificity for differentiating tumor from inflammation, thus making it an attractive biomarker for treatment response in rectal cancer. The goal of this research is to provide an image-based approach for determining which patients would be optimal candidates for rectal-sparing treatment.

Simpson Pic 1.pngDr. Simpson is also working towards a secondary long-term project aimed at developing a functional imaging technique that is capable of imaging the immune response within tumors. Emerging evidence suggests that tumor immune cells play a key role in tumor behavior, and multiple studies have shown improved outcomes in various cancer types with immunotherapy agents such as ipilimumab and nivolumab. However, responses to these 

Simpson Pic 2.png therapies are only seen in a fraction of patients, and presently there are no reliable methods to identify which patients will benefit from these therapies. His research group is developing a novel radiotracer, 68Ga-tilmanocept (left), as a putative "immuno-imaging" agent. This tracer is a receptor-targeted molecule that binds to receptors found on tumor-associated macrophages that have been shown to inhibit immune responses within tumors. This agent has potential as a non-invasive prognostic marker that may help to direct cancer therapy at an individual level.

Dr. Kevin Moore is an Associate Professor and the Deputy Director of the Division of Medical Physics and Technology. Together with physicist and physician collaborators, he is developing novel knowledge-based treatment planning approaches in stereotactic radiosurgery for benign and malignant tumors. Moore Pic 1.png

Knowledge-based planning involves applying prior knowledge from large datasets of previously treated patients in order to optimize treatment planning of new patients, significantly improving plan quality.  Initially applied to head/neck and prostate cancer patients undergoing conventional fractionation, Dr. Moore is also applying this novel approach to optimizing clinical trials.

Sharabi Lab
Dr. Sharabi.pngThe Sharabi lab is focused on understanding the fundamental interactions between radiation and the immune system and identifying strategies to combine radiation with immunotherapy. Dr. Sharabi has a M.D and Ph.D. in Immunology and completed his Residency in Radiation Oncology at Johns Hopkins. His long term goal is to directly advance patient care and improve outcomes in cancer patients though translational research.

While at Johns Hopkins, Dr. Sharabi published one of the first studies combining stereotactic radiation with anti-PD-1 checkpoint blockade immunotherapy. His work identified a role for stereotactic radiation in inducing antigen specific anti-tumor immune responses and that antigen cross presentation may be required for the immune stimulatory effects of radiation. Additionally his work demonstrated that stereotactic radiation can induce antigen-specific memory T-cells.

Sharabi Pic 1.pngIn order to translate these findings into the clinic,Dr. Sharabi is involved in a number of clinical trials. He is a Co-Investigator on J1382: A Pilot Study of Stereotactic RadioSurgery combined with Ipilimumab in Patients with Newly Diagnosed Melanoma Metastases in the Brain and Spine. He is also a Co-Investigator on J13158: Evaluation of Immunologic Responses in HPV-Associated Oropharyngeal Carcinoma Patients Receiving Chemoradiation Therapy at Johns Hopkins Hospital. At UC San Diego he is the Principle Investigator on a Phase II Randomized study to determine the benefit of adding SBRT to checkpoint blockade immunotherapy.
