Welcome to Stanford Radiation Oncology, Olga Stafford! Dr. Stafford joins our department as a clinical assistant professor (radiation physics). Her professional and research interests focus on the safe clinical integration of advanced technologies in radiation oncology, including AI-support workflows, stereostatic radiosurgery, small-field dosimetry, adaptive radiation therapy, and practical QA strategies that support safe and scalable implementation in community practice.

“I look forward to contributing to Stanford’s clinical, educational, and collaborative mission,” she said. Let’s all wish Dr. Stafford a warm welcome!

We are thrilled to welcome (back) Zhuoran Jiang to our department as a clinical assistant professor of radiation oncology (radiation physics)! Dr. Jiang recently completed her medical physics residency in our department.

Her research focuses on developing artificial intelligence-based methods to improve radiation therapy in the realm of image guidance, deformable image registration, and dose verification.

As of yesterday, our recently graduated residents have departed to begin their new journeys. Please join us in congratulating our Medical Physics residents, Veng Jean Heng and Zhuoran Jiang, and our Radiation Therapy residents, Zachary B. White II, Daniella (Dasha) Klebaner, Abass Conteh, Iris Eke, and Wilson Mai (left to right)!

While we are sad to see them go, we are incredibly proud to see them step into their next chapters as future leaders in medicine. A fond farewell and heartfelt congratulations to our class of 2026!

Please join us in wishing Dr. John Byun, MD, a fond farewell as he moves on to his next chapter! Since joining us in July 2024, Dr. Byun has been a vital part of our team and growing network. His clinical expertise, dependability, and collaborative approach have made a lasting, positive impact on both our patients and his colleagues. We are deeply grateful for John’s dedication and contributions during his tenure and wish him the very best.

"Every little edge we can get, we can take advantage of."

Dr. Bill Loo, MD, PhD, describes the philosophy behind the years-long effort to bring compact proton therapy to Stanford.

We are thrilled to see our department’s hard work featured in The Mercury News today, featuring Dr. Susan Hiniker, MD, and Dr. Loo! Space on a busy medical campus is always at a premium, which historically made massive, multi-story proton systems impossible to install. By embracing a compact, single-room particle accelerator, our team successfully converted an existing treatment vault to bring this precise, tissue-sparing technology directly to patients in need.

Stanford’s first proton therapy patient is 7. His case shows why the treatment matters A tech breakthrough fits a specialized type of radiation treatment into standard treatment rooms, including at Stanford Medicine.

Clinical innovation meets life-changing patient care! Our department was recently spotlighted by People Magazine following the successful treatment of our first patient in the world’s most compact proton therapy suite.

For pediatric patients with tumors located near critical structures like the brain stem, precision is everything. This technology allows our team to minimize long-term side effects by protecting surrounding healthy tissue.

We are incredibly proud of our team for their commitment to redefining what is possible in cancer treatment, and we are cheering on our brave first patient as he completes his care.
