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, 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. His research work is widely published in the top venues in these areas. He has supervised many PhD and 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, and has contributed repeatedly tot he community through conference organization committees and editorial boards. His teaching activities revolve mainly around the systems area including networking, operating systems, computer organization and kernel/system programming.
