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. -

Mohammad Shahrokh Esfahani
Assistant Professor of Radiation Oncology (Radiation and Cancer Biology)
BioI lead a computational oncology laboratory that develops machine learning and statistical methods for high-dimensional genomics, with particular expertise in Bayesian and uncertainty-aware modeling to integrate prior biological knowledge with large-scale datasets.
Our research centers on liquid biopsy analytics—especially cell-free DNA (cfDNA)—to noninvasively quantify genetic and epigenetic states relevant to cancer detection, monitoring, and tumor evolution. We developed EPIC-seq, a fragmentomics-based method that uses cfDNA fragmentation patterns to infer regulatory activity and gene expression programs, providing a scalable framework for epigenetic profiling from blood.
A core methodological focus of the lab is enabling reliable inference in extremely low signal-to-noise settings that are typical of cfDNA and early-stage disease. We build robust, interpretable models and benchmarking frameworks that support clinical translation, with the long-term aim of democratizing access to sensitive, minimally invasive cancer diagnostics. -
Junming Seraphina Shi
Postdoctoral Scholar, Radiation Biology
BioI am a postdoctoral fellow at Stanford University, jointly mentored by Dr. Mohammad Shahrokh Esfahani and Dr. Md Tauhidul Islam. My research focuses on developing robust statistical machine learning methods for noninvasive, cost-effective cancer diagnostics, with applications in early detection, treatment monitoring, and precision oncology.
I received my Ph.D. from UC Berkeley, where my dissertation centered on advancing biostatistical machine learning approaches for complex biomedical challenges. My work addressed causal inference for continuous treatments, bias and measurement patterns in ICU electronic health records, and deep learning–based biclustering and prediction of cancer-drug responses. Across these projects, I developed interpretable and scalable tools for analyzing high-dimensional, multimodal clinical data.
At Stanford, I continue to build novel statistical learning frameworks tailored to real-world clinical needs—particularly through the analysis of liquid biopsy (cell-free DNA) and cancer imaging data. My current work aims to improve cancer detection and monitoring, with a focus on noninvasive, accessible, and clinically meaningful solutions to pressing challenges in oncology. I enjoy interdisciplinary collaborations and working across fields to drive innovation in biomedical research. Deeply committed to cancer research, I aim to bridge rigorous computational methodology with patient-centered impact by designing tools that are scalable, equitable, and translational. -
