Dr. Zang-Hee Cho received Ph.D. at Uppsala University (Sweden) in 1966 and has been faculty at the University of Stockholm and University of California-Los Angeles. In 1979, Dr. Cho moved to Columbia University as a Professor of Radiology (Physics) and served as a co-Director of Columbia University Imaging Center until 1984 before he joined University of California, Irvine (UCI). Since 1985, Dr. Cho was the Professor of Radiological Science at University of California at Irvine until 2006. From 2006 to 2014, Professor Cho, the University Professor at the Neuroscience Research Institute, Gachon University of Medicine & Science, Incheon, Korea. Dr. Cho moved to Advanced Institutes of Convergence Technology (AICT), Seoul National University, as a Distinguished Research Fellow, since 2015. Professor Cho has been a pioneer in Positron Emission Tomography (PET) and Magnetic Resonance Imaging since the inception of the computerized tomography (CT) in 1972. He was the first one who pioneered world’s first "Ring PET" in 1975 and its nuclear detector "Bismuth Germanate Oxide (BGO)" in 1976, both of which revolutionized modern brain-imaging. More recently, professor Cho pioneered the first PET-MRI (Proteomics 2008) demonstrating that in-vivo submillimeter high resolution molecular imaging is possible. This pioneering work now accepted as an important new approach to the molecular imaging in human brain imaging in-vivo. Among the numerous honors and awards, Professor Cho was elected as a member of the US National Academy of Sciences- Institute of Medicine in 1997.

Dr. George R. Lee received his medical degree from the Medical College of Georgia. He subsequently completed his internship in internal medicine at the University of Alabama, School of Medicine and his neurology residency at Vanderbilt University Medical Center. He continued his training at Vanderbilt University as a clinical neurophysiology fellow and served as the chief fellow. He currently holds an appointed position as Assistant Clinical Professor of Neurology with the Department of Neurology at Vanderbilt University Medical Center. He is the president and chairman of the board for Real Time Neuromonitoring Associates, PC and affiliated entities. He also serves as the medical director of the Vanderbilt Neurodiagnostic Technologist Training Program for which he helped found and obtain accreditation. His clinical focus is on providing intraoperative neuromonitoring and neurodiagnostic studies. Dr. Lee maintains licensure in Tennessee and 46 other states plus the District of Columbia. He has served on the Board of Directors of the American Society of Neurophysiological Monitoring (ASNM) and as its president and chairman of the board. He also has served on the board of the Tennessee Medical Association, board of Tennessee Medical Education Fund, Independent Medicine's Political Action Committee of Tennessee (IMPACT), the Tennessee Physician Leadership College Steering Committee, and the national Committee on Accreditation for Education in Neurodiagnostic Technology (CoA-NDT). He frequently presents at national and international conferences on the topics of intraoperative neuromonitoring practices, quality, evidence, medicolegal, and business. He has received leadership awards by the American Medical Association and the American Academy of Neurology and most recently received an outstanding entrepreneur award from Emory University.
