Short Bio.

Professor Bensaou is an Associate Professor of Computer Science and Engineering at HKUST. Prior to that he was a Senior Member of Technical Staff, and the Leader of the Networks strategic research group at Singapore's national R&D Centre for Wireless Communications (CWC, now under A*Star I2R after a merger of two such centres). He has earned his Doctorate degree from Université Paris 6 Jussieu, France, under the co-supervision of Prof. Guy Pujolle and Dr James W. Roberts at France Telecom Research Labs where he did all his PhD research within the "high speed networks teletraffic research group".
Professor Bensaou's research interests are diverse but lie primarily in the area of resource allocation, resource sharing and quality of service and teletraffic in network systems, including wireless local- and wide-area networks, information-centric networks, data centre networks, software-defined networks and the Internet at large. He has supervised 13 PhD theses and about 20 MPhil/MEng theses (both at HKUST and NUS when he was with the CWC in Singapore). He is a Senior member of IEEE and a member of ACM.
