Description of Clinical Expertise

Dr.Dong is familiar with radiation dosimetry and use of images in radiation oncology for setup (IGRT) and treatment planning. He was involved in several auto-segmentation projects using deformable image registration or machine learning methods. In addition, Dr.Dong worked extensively in the technical commissioning in three proton therapy centers (Hitachi Synchrotron at MD Anderson Cancer Center in 2005-2008, Varian first ProBeam pencil beam scanning at Scripps Health in 2012-2016, and IBA multi-room cyclotron-based system with upgraded dedicated pencil beam scanning technology since 2017).

Description of Research Expertise

My research interests are always motivated by clinical needs. As a medical physicist, the use of advanced technologies to improve clinical outcomes or clinical efficiencies is always interesting to me. Throughout the years, I have been interested in intensity-modulated radiation therapy, which includes proton therapy and automated treatment planning; I am interested in adaptive radiotherapy beyond anatomical changes of patient’s anatomy; I am interested in imaging, which provides rich information about the patient (spatially or biologically); I am interested in novel treatment techniques, which includes the recent hot topic on ultra-high dose-rate radiation therapy (FLASH). I have published over 220 peer-reviewed papers and 15 book chapters. My publication h-index is around 62. I plan to continue my innovative research through close collaboration with researchers internally and around the world.
