Wei Liu, Ph.D.

Dr. Wei Liu is Professor of Radiation Oncology and Research Director of Division of Medical Physics of Mayo Clinic in Arizona. He is a Fellow of American Association of Physicists in Medicine (AAPM). He was the recipients of the Mayo Clinic Alumni Association Early Career Award in 2025, the John S. Laughlin Young Scientist Award of AAPM in 2019 and the NIH/NCI Early Career Award (K25) in 2012. A scientific term Liu Limit was named after him. Leading radiotherapy company, Varian Medical Systems, has adopted methods that he developed as the basis for its commercial treatment planning solutions.

Currently he serves as Co-Chair of Particle Therapy Co-Operative Group Thoracic SubCommittee. He is an Associate Editor of International Journal of Radiation Oncology Biology Physics, IEEE Transactions on Medical Imaging (TMI), and Medical Physics and an Editorial Board member of Radiotherapy & Oncology and Physics in Medicine and Biology. He also serves in the Imaging Technology Development study section and Special Emphasize Panel of NIH and as a reviewer for the Netherlands Organization for Scientific Research (NWO/ZonMw), KWF Kankerbestrijding (Dutch Cancer Society), and Austrian Science Fund (FWF).

His research focuses on: (1) application of operations research techniques in radiotherapy; (2) robustness quantification; (3) accurate and fast dose and LET calculation; (4) motion management; (5) patient outcomes study; and (6) application of artificial intelligence in radiotherapy, especially generative AI such as large language models in radiation oncology.
