Research
Dr. Hsi-Chun Alister Wang received the B.S. degree in Chemical Engineering from the National Taiwan University in 1985 and the Ph.D. degree from the University of Southern California in 1995.
Dr. Wang was a post-doc research associate in Department of Chemical Engineering at University of Southern California from 1995 to 1997. In September 1997, he had been with the Non-Destructive Testing Laboratory (NDT Lab) at Institute of Nuclear Energy Research (INER) in Taiwan. From 1998 to 2000, he was Assistant Professor in the Department of Graphic Communications and Technologies at Shih-Hsin University, which is famous for media production. Since August 2000, he has been with the Department of Graphic Arts and Communications, in the College of Technology, at National Taiwan Normal University, where he has been Assistant Professor, Associate Professor, Department Chairman and currently is Professor.
Dr. Wang's research interests are in the areas of signal/image processing and anti-counterfeiting technologies.
He has authored more than 50 technical publications in the national and international conferences and journals. Dr. Wang is a member of IEEE, SPIE, IS&T and life member of IPPR (in Taiwan).
He received several paper awards in the international and local academic conferences and he is the inventor of 9 patents (two US patents and seven ROC (Taiwan) patents).
He won the Gold Medal in the
National Invention Award (Ministry of Economic Affairs) in 2011,
and Award for Excellent Contributions in Technology Transfer (National Science Council, now Ministry of Science and Technology) in 2013.
Dr. Wang is the principal investigator of HalfMediaLab which is applying digital halftoning techniques to value-added media design. Dr. Wang has been a die-hard photographer and stamp-collector for 20+ years.
