Weijun Xiong, Ph.D., DABR, began his journey in medical physics during his undergraduate and doctoral studies, focusing on the fundamental physics of particle interactions, the development of radiation detectors, and the application of radiation in medicine and radiation therapy. He completed a medical physics residency in radiation oncology, gaining comprehensive training in advanced techniques such as IMRT and Monte Carlo simulation in radiotherapy. His early research included projects on Monte Carlo development and biological modeling in radiation therapy.
Dr. Xiong’s professional career began at Memorial Sloan Kettering Cancer Center, where he served as a faculty medical physicist and oversaw all aspects of medical physics operations at an independent regional site. He later became a founding medical physicist at a new proton therapy center, playing a pivotal role in the facility’s acceptance testing and the commissioning of various imaging modalities. He also led the development of adaptive radiation therapy programs and explored emerging techniques such as FLASH radiotherapy.
Currently, Dr. Xiong is dedicated to advancing clinical care, academic research, and education in medical physics. His research interests include innovative imaging guidance, molecular imaging, radiation transport modeling, treatment planning technologies, AI-driven informatics, and personalized radiation therapy. As a funded researcher, he has authored over 60 peer-reviewed journal articles and more than 180 national and international conference abstracts.
As a faculty member, Dr. Xiong has mentored more than 10 medical physics residents and has played a significant role in academic training, delivering lectures on core curriculum topics. He actively participates in initiatives addressing global inequities in cancer care while promoting diversity in research.
Looking ahead, Dr. Xiong remains committed to integrating scientific discovery into clinical practice, improving patient outcomes, and shaping the future of medical physics through innovation, collaboration, and mentorship.
