Dr. Sheng-Wei Chen (also known as Kuan-Ta Chen) is an assistant research fellow at the Institute of Information Science and the Research Center for Information Technology Innovation (joint appointment) of Academia Sinica. He received his Ph.D. in Electrical Engineering from National Taiwan University in 2006, and his B.S. and M.S. in Computer Science from National Tsing Hua University in 1998 and 2000, respectively. Prior to taking his academic path, he was known as a programmer specialized in Windows and system programming, a technical writer of four books, a technical lecturer of various programming courses, and a shareware developer.

His research interests include Internet & Multimedia Quality of Experience (QoE) management, Internet measurement, VoIP, network security, and online games. Much of his recent work focused on the human factors in network systems, including QoE measurement, user perception and behavior modeling, and QoE-aware system design. He received a Best Paper Award (with Ieng-Fat Lam and Ling-Jyh Chen) in IWSEC 2008. He is a member of ACM, IEEE, IICM, and CCISA.
