Yushen Qian, MD
Clinical Associate Professor, Radiation Oncology - Radiation Therapy
BioDr. Qian is a board-certified radiation oncologist and a Clinical Associate Professor in the Stanford University School of Medicine, Department of Radiation Oncology.
In his clinical practice, he sub-specializes in genitourinary (including prostate and bladder cancer) and Head and Neck malignancies, but also treats a broad spectrum of other disease subsites including lung/thoracic, gastrointestinal, brain, lymphoma, and breast tumors. For each patient, he develops a comprehensive, individualized, and compassionate care plan customized to individual needs. His goal is to deliver the most effective cancer treatment to help patients enjoy the best possible health and quality of life.
In addition to his clinical practice, Dr. Qian serves as the Medical Director of Radiation Oncology at Stanford South Bay Cancer Center. He also serves as the Radiation Oncology Network Director of Clinical Research and has spearheaded opening of multiple NRG Oncology clinical trials at Stanford South Bay Cancer Center.
Dr. Qian is also actively involved in the Stanford Radiation Oncology residency program. He created and oversees a monthly mentorship roundtable series to assist residents with multiple aspects of their clinical training and career progression.
Outside of work, Dr. Qian enjoys spending time with his family and exploring the great outdoors of Northern California. -

Yuan James Rao, MD
Associate Professor of Radiation Oncology (Radiation Therapy)
BioDr. Yuan James Rao is a board-certified radiation oncologist with Stanford Health Care. He is also an associate professor of radiation oncology and the associate director of proton therapy in the Department of Radiation Oncology, Division of Radiation Therapy at Stanford University School of Medicine.
As a radiation oncologist, Dr. Rao treats chest (thoracic) and head and neck cancers. He specializes in using proton therapy, a type of high-energy radiation therapy that precisely targets cancer cells while sparing surrounding tissue. The proton therapies he uses include 3D conformal radiation therapy, intensity modulated radiation therapy, and stereotactic body radiation therapy. He also uses brachytherapy, which treats cancer by placing radiation sources inside or very close to a tumor.
Dr. Rao’s research interests include the use of proton therapy in treating various cancers. He has also studied the role of machine learning and advanced imaging techniques to improve radiation treatments. In addition, Dr. Rao has investigated ways to integrate immunotherapy into radiation treatment regimens.
Dr. Rao has published his work in and served as an ad hoc reviewer for several peer-reviewed journals, including Nature Cancer, Frontiers in Oncology, Advances in Radiation Oncology, and PLOS One. In addition, he has co-written chapters in books including Perez & Brady’s Principles and Practice of Radiation Oncology and Pocket Guide to Radiation Oncology. He has presented his work nationally and internationally, including at meetings of the American Brachytherapy Society (ABS), American Society for Radiation Oncology (ASTRO), and European Society for Radiation Oncology.
Dr. Rao is a member of the ABS and ASTRO. -

Mrinmoy Sanyal
Casual - Non-Exempt, Radiation Oncology - Radiation Therapy
BioMrinmoy Sanyal obtained his undergraduate and master's degree in Human Physiology at the University of Calcutta. He did his Ph.D. in Biochemistry at All India Institute of Medical Sciences, New Delhi, working on reproductive immunology, with the focus on trophoblast invasion and differentiation and their role in human blastocyst implantation. Then, he moved to Stanford University for a postdoctoral fellowship on the role of transcription factor Pbx1, a leukemia proto-oncogene, on B cell development. Currently, he is Research Scientist at Department of Biochemistry, Stanford University. His work covers various topics, including B cell responses to viral infection and vaccination, human primary immunodeficiency, and biology of lymphocyte development and function and to elucidate etiology of immunological disorders.

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.
