JungHyun was born on Feb. 10, 1963 in Seoul. He received the B.S. degree in Computer Engineering from Seoul National University in 1988, and the M.S. degree in Computer Science from the University of Cincinnati in 1991. He is now finishing his Ph.D. degree in Computer Science from the University of Southern California (USC). Since 1991, he has worked in the Programmable Automation Lab, a research unit within the Institute for Robotics and Intelligent Systems (IRIS) at USC. With his advisor Dr. Aristides Requicha who is called a pioneer in geometric modeling, he has developed novel software systems for geometric reasoning that blend the techniques from both computational geometry and artificial intelligence. His short-term goal is to write a distinguished Ph.D. dissertation, mid-term goal is to be a leading scientist in the field of applied computational geometry, and life-term goal is to become an artist in photo and computer animation.
