Welcome to the Department of Radiation Oncology at the University of California, Irvine (UCI) School of Medicine. Whether you are a patient, family member, referring physician, student or other interested party, our team of experts are here for you.

It is an exciting time in cancer care as patients are living longer, better, and more fulfilling lives than ever before. Precision medicine has allowed us to provide an unprecedented level of personalization with respect to treatment, accounting for the clinical, biological, and psycho-social considerations which make each human being unique. What that means at UCI is that no two patients are ever treated the same. Instead, our renowned physicians take pride in crafting customized, hand-tailored cancer therapies using the most advanced scientific breakthroughs and technologies— often incorporating innovative research originating from right here at UCI— to not only target the disease, but more importantly, treat each person as a whole. We take pride in offering a higher level of expertise, compassion, and accessibility than anybody else— and our patients should expect nothing less.

Our doctors are healers, educators, researchers, and internationally respected thought leaders who are working tirelessly to pioneer the next generation of treatments for cancer patients. For us, cancer is not just a job; it represents an around-the-clock, lifetime passion. Through cutting-edge research including the integration of bench-to-bedside discoveries and clinical trials, we are committed to helping patients and are proud to have the entire weight of a world class institution behind us.

As part of one of the nation's premier Cancer Centers and the only academically affiliated medical center in Orange County, our team looks forward to meeting you. On behalf of our prestigious faculty and staff, I proudly invite you to learn more about what academic medicine at UCI can offer you or your loved ones.
