Bio sketch and interests:  Dr. Yuan received his PhD degree in experimental nuclear physics from Hampton University in 2002, and worked as a research fellow for several years before completing his residency training at Duke University in 2017. Over the years, Dr. Yuan’s research has focused on knowledge guided treatment planning to improve planning quality and efficiency. His research has made an impact on the optimization of IMRT planning, and has been published in peer review journals. It has also recently been commercialized by Varian Medical Systems. His current research efforts are along two directions; one is the application of the knowledge guided method to quality assure and quantitatively assess the fidelity of treatment plans, and the other is to expand the method to automate the whole RT planning process. Dr. Yuan is also interested in developing new methods and rapid learning processes to take advantage of growing treatment planning and treatment outcome data in radiation oncology.
