Professor Lee graduated from Washington University School of Medicine (USA) in 1973. He completed his residency training at Mallinckrodt Institute of Radiology and joined the faculty in 1977. He became a full professor in 1986. Prof Lee left Washington University in 1991 for the University of North Carolina at Chapel Hill, where he served as chair of radiology before relinquishing his administrative duties in 2007. 

Prof Lee served as a Visiting Professor at National University of Singapore (2014 – 2016). He now devotes his time to patient care, clinical research and mentoring the next generation of radiology leaders. 

Prof Lee is a world-class expert in computed tomography (CT) and magnetic resonance imaging (MRI) and his primary area of expertise is abdominal imaging. 

In the United States and abroad, Prof Lee is known as a pioneer in the clinical utility of CT and MRI of abdominal and pelvic organs. He has written and edited seven major textbooks. His best-known book, Computed Body Tomography with MRI Correlation, is in its fourth edition and was published in 2006. He also has published more than 160 articles in refereed journals. 

His research focuses on the comparison between CT and MR imaging for various abdominal and pelvic disorders, and identifies the impact that use of these new technologies can have on patient care. 

Prof Lee has also focused on enhancing productivity in academic radiology departments.
He has delivered numerous invited lectures nationally and internationally. He has served leadership positions in many professional radiologic organizations, including the office of president for the Society of Computed Tomography and MRI, the Society of Chairmen of Academic Radiology Departments and the American Roentgen Ray Society (ARRS). 

Prof Lee received Gold Medal from Asian Oceanian Society of Radiology, ARRS and Society of Computed Body Tomography/MRI. He was the recipient of Washington University School of Medicine Alumni Achievement Award and is an Honorary Member of Korean Society of Radiology as well as Japanese Society of Radiology.
