The 9th GCB Biomedical Science and Engineering Symposium was jointly held by the Global Center for Biomedical Science and Engineering of the Graduate School of Medicine and the Department of Radiation Oncology of Stanford University on August 20 and 21. It was held in a hybrid format, using the Centennial Hall of the School of Medicine as the on-site venue. Top-class researchers from Japan and abroad gathered for two days of presentations and discussions on cutting-edge research in the field of medical science and engineering.

It started with the opening comments from Professor Quynh-Thu Le of Stanford University and consisted of four sessions: one day on medical physics and radiation therapy, and the second day on radiation biology and diagnostic imaging. We welcomed Dr. Jin-Min Nam from Kyoto University, Dr. Sodai Tanaka from the Quantum Science and Technology Agency, Dr. Burcin Unlu from Boğaziçi University, Dr. Paul Sperduto from Duke University, Dr. Greg Zaharchuk from Stanford University on site.

Also as online lectures from overseas, we had Dr.Xuejun Gu from Stanford University, Dr. Anussara Prayograt from Chulalongkorn University, and Dr. Mary Helen Barcellos-Hoff from the University of California San Francisco. We had lively discussions in each section and concluded the event on a high note with a closing from the deputy director of the GCB Dr. Yuji Kuge.

The event was attended by a total of 81 people on-site and more than 200 people online from over 40 countries. Since many participants were unable to attend all the lectures due to time differences and other reasons, the recorded videos were distributed on demand at a later date.
