Elham Rahimy, MD
Clinical Assistant Professor, Radiation Oncology - Radiation Therapy
BioDr. Rahimy is a radiation oncologist who treats patients with brain, spine, gastrointestinal, and metastatic tumors. She received her medical training at Yale, followed by residency at Stanford. She is a Clinical Assistant Professor with the Stanford Department of Radiation Oncology.
Dr. Rahimy's technical expertise includes CyberKnife Radiosurgery and MRI-guided adaptive planning. She is also actively involved in radiation oncology research and clinical trials. Her interests include improving patient and resident education, and enhancing patient quality of life and survivorship. She leads quality initiatives as a Quality Physician Improvement Leader, and serves as the Medical Student Clerkship Director. -
Yuan James Rao, MD
Associate Professor of Radiation Oncology (Radiation Therapy)
BioDr. Yuan James Rao is an Associate Professor of Radiation Oncology, and Co-Director of Proton Therapy at Stanford University. In 2026, Dr. Rao co-led the team at Stanford that treated the world’s first pediatric and adult patients with ultra-compact upright proton therapy. Dr. Rao’s professional goal is to develop the world’s most advanced proton therapy program at Stanford University.
Proton therapy is a remarkable form of radiation treatment that uses heavy charged particles (protons) accelerated to approximately two-thirds the speed of light. The unique physics of protons allows the radiation to stop within a defined distance in the body, whereas standard x-ray therapy continues to deposit radiation after treating the tumor (known as “exit dose”). By reducing exit dose, protons may reduce normal tissue exposure to radiation, which is particularly beneficial for children and young adults with cancer, and patients requiring a second course of radiation. Dr. Rao currently coordinates the Stanford Radiation Oncology Department’s clinical, research, and education efforts related to proton therapy.
Dr. Rao’s clinical practice focuses on the care of patients with Head and Neck cancer, and Thoracic cancers. His goal is to provide the highest quality care to his patients, using the most appropriate technology. This may include proton therapy but also potentially other techniques such as intensity modulated radiation therapy (IMRT), stereotactic body radiation (SBRT), MR-guided radiotherapy, 3D conformal radiotherapy, or other technologies. Nearly all radiation technologies are available at Stanford University, and thus Dr. Rao and his Radiation Oncology colleagues are well positioned to choose the best treatment for every patient.
Dr. Rao trained at the prestigious Mallinckrodt Institute of Radiology at Washington University in St. Louis, and during residency was among the first physicians in the world to use the Mevion S250 proton therapy device and the ViewRay MRI-guided radiotherapy device. Dr. Rao has traveled to UCSF, MD Anderson, Johns Hopkins University, University of Pennsylvania, Medical University of Vienna, and University Medical Center Utrecht to learn about various advanced radiotherapy techniques including MR-guided radiotherapy, brachytherapy, and proton therapy.
Prior to his role at Stanford, Dr. Rao was a physician at George Washington University in Washington, DC and held the positions of Associate Professor of Radiation Oncology and Biomedical Engineering (by courtesy), and Assistant Professor of Neurosurgery (by courtesy). He was also the founding Director of Brachytherapy, and implemented programs for gyn, head and neck, prostate, and skin radiation implants using high dose rate (HDR) techniques. He was honored as a Washingtonian Top Doctor for each of the years that he practiced in DC, and Dr. Rao has treated members of Congress with radiotherapy (public information).
Dr. Rao is a prolific researcher with more than 50 peer-reviewed publications. He is an expert in proton therapy, head and neck cancer, thorax cancers, gyn cancers, GU cancers, brachytherapy, artificial intelligence, machine learning, image analysis and large database "big data." He is co-author of the ‘Endometrial Cancer’ chapter of the 8th edition of Perez and Brady’s Principles and Practice of Radiation Oncology, the world’s most widely used reference textbook in the field. He regularly gives invited talks nationally and internationally. Dr. Rao has been grant funded by the American Cancer Society.
Dr. Rao is a respected educator and mentor, and has taught numerous engineering/physics students, medical students and residents; many of whom have gone on to become successful physicists, scientists, entrepreneurs, and physicians. -
Bijie Ren
Visiting Instructor, Radiation Oncology - Radiation Physics
BioBijie Ren is a quantitative biologist as well as a pro bono academic advisor for the SATORI Institute for Complexity and Emergence (SICE). Inspired by electrical engineering and synthetic biology courses at MIT, he developed a profound interest in integrating digital logic into synthetic biotechnology. He earned his Ph.D. in Quantitative Biology from UC San Diego and was a Postdoctoral Fellow at the Carnegie Institution for Science at Stanford University. His expertise lies at the intersection of AI and synthetic biology, built a high throughput cellOS to quickly Decode-Design-Recode novel species, with a specific focus on engineering microalgae to foster a better ocean ecosystem, discovery of anti-aging chemicals/peptides with new technology and real-world ground-truth data generation for virtual cell training and AlphaFold improvement. The whole pipeline can quickly help scientists to discover novel protein targets involved in aging process, design new chemical/peptide to target on these proteins and validate their effect in the wet lab to see if these molecules can extend single cell life span. The ingredients can be used for cosmetic, cosemtic injection, healthcare food and pharmacy sequentially. And with powerful cell factory and new synbio technology, he can reduce the R&D and manufacture cost by log scale.
In his advisory role at SICE, he also collaborated with distinguished faculties from top universities to initiate local "Labrary", aiming to empower young students to succeed in both academia and industry. -
