Stefan Winkler is Deputy Director at AI Singapore and Associate Professor (Practice) at the National University of Singapore. Prior to that he was Distinguished Scientist and Director of the Video & Analytics Program at the University of Illinoisâ Advanced Digital Sciences Center (ADSC) in Singapore. He also co-founded two start-ups and worked for a Silicon Valley company. Dr. Winkler has a Ph.D. degree from the Ecole Polytechnique FÃ©dÃ©rale de Lausanne (EPFL), Switzerland, and a Dipl.-Ing. (M.Eng./B.Eng.) degree from the University of Technology Vienna, Austria. He is an IEEE Fellow and has published over 150 papers and the book âDigital Video Quality.â He was Associate Editor of the IEEE Transactions on Image Processing (2009-2018) and the IEEE Signal Processing Magazine (Standards Column) (2012-2015). He is a member of the IVMSP Technical Committee of the IEEE Signal Processing Society, Executive Committee Member of the IEEE Singapore Section and the IEEE Singapore Signal Processing Chapter. He has served on the organizing committees of numerous conferences and workshops, including area chair of ICIP and ICME, general chair of QoMEX 2014, as well as the QoMEX Steering Committee (2014-2017). He has also contributed to video quality standards in VQEG, ITU, ATIS, VSF, and SCTE. His research interests include video processing, computer vision, machine learning, perception, and human-computer interaction
