As a radiation oncologist, Dr. Wei’s clinical practice focuses on the comprehensive care of children and adults with cancer. Dr. Wei received his medical and graduate degrees at the University of California, Irvine, as part of the Medical Scientist Training Program.  He then completed his internal medicine internship and radiation oncology residency at the University of California, Irvine. He trained with Dr. Nisar Syed and Dr. Ajmel Puthawala in interstitial brachytherapy and hyperthermia techniques.  He served as Chief Resident for the final 2 years of residency.

Dr. Wei recognizes the unique needs of cancer patients and their families after his own father was treated for head and neck cancer.  His philosophy on care is to empower his patients with education on their cancer and treatment options, enable patients and caregivers to make informed medical decisions, and provide them access to the most advanced radiation treatments such as intensity modulated radiotherapy, stereotactic radiosurgery, interstitial brachytherapy, and proton therapy.

Over the past decade, Dr. Wei has published over 21 peer reviewed manuscripts and 3 book chapters in journals such as Radiotherapy and Oncology, Practical Radiation Oncology, Medical Dosimetry, and Molecular and Cell Biology. His clinical interests are in cancer biology, pediatrics, brachytherapy, quality and safety, and palliative care. Dr. Wei received his PhD from the lab of Dr. Wen-Hwa Lee who cloned the retinoblastoma tumor suppressor gene, and did pioneering research on the mechanism of tumor suppressors in cancers.  He has given oral presentations at the American Society for Radiation Oncology (ASTRO) and Radiological Society of North American (RSNA) Annual Meeting, and he was awarded the American Society for Clinical Oncology Conquer Cancer Foundation Award, and RSNA Roentgen Research Award.

Dr. Wei is a member of ASTRO, Los Angeles Radiological Society, American College of Radiation Oncology, and American Brachytherapy Society.   Dr. Wei is on the medical staff at Long Beach, Orange Coast Memorial, and Saddleback Memorial Medical Center.
