Chun-Yang Chen (also known as Kuan-Ta Chen)
Assistant Research Fellow, Institute of Information Science, Academia Sinica
Director, Multimedia Networking and Systems Lab

Dr. Chun-Yang Chen (also known as Kuan-Ta Chen) received his B.S. and M.S. in Computer Science from National Tsing Hua University in 1998 and 2000, respectively. From 2001 to 2005, he was a research assistant in the Institute of Information Science, Academia Sinica as the military service, where he developed document management systems and XML-based software. He received his Ph.D. in Electrical Engineering from National Taiwan University in 2006. Since then he joined the Institute of Information Science, Academia Sinica as an Assistant Research Fellow.

His research interests include Internet measurement, Internet QoS (Quality of Service) and QoE (Quality of Experience), VoIP, network security, and online gaming. Much of his recent work focus on the human factors in network systems, including user experience measurement, user behavior modeling, and QoE-aware system design. He is a member of ACM and IEEE.
