Zhang Hongzhi

Research areas: Radiation oncology physics, advances and clinical applications of proton and heavy ion radiotherapy technology.

Cutting-edge technology: With many years of experience in research and clinical practice in radiation oncology physics, I possess profound expertise in the physical principles, dosimetry, and quality control systems of proton and heavy ion radiotherapy. I was invited to give a special report on "Advances and Prospects of Proton and Heavy Ion Radiotherapy Technology" at the academic conference of the Chinese Society of Radiation Oncology.

Areas of expertise: proton and heavy ion radiation physics, quality control of radiotherapy equipment, and medical physics education.

Academic Highlights and Core Values: Researcher at the National Cancer Center/Cancer Hospital of the Chinese Academy of Medical Sciences; Distinguished Researcher at the Department of Engineering Physics, Tsinghua University; Honorary Chairman of the Proton and Heavy Ion Radiotherapy Professional Committee of the China Association for the Promotion of Human Health Science and Technology; Advisor to the Physics Group of the Chinese Society of Radiation Oncology. Formerly served as Vice Chairman and Head of the Physics Group of the Chinese Society of Radiation Oncology, and Director of the Editorial Department of the *Chinese Journal of Radiation Oncology*. Received the Special Contribution Award for Radiation Oncology from the Chinese Society of Radiation Oncology in 2011.
