| Biography |
I attended High School at
Lycée Emir Abdelkader (of Algiers Algeria), known for its high quality teaching and graduates such as
literature Nobel Prize
winner Albert Camus, Paul Robert (Le Robert), or Dr. Elias Zerhouni the former Director of the US NIH, among many others.
After obtaining the Baccalauréat, I spent five years at the University of Science and Technology Houari Boumediene of Algiers Algeria, where I obtained a State Engineering degree in Computer Science. In my senior year I fell under the spell of computer networking, and decided to pursue this interest.
I took the National exam for postgraduate scholarships and ranked second over the top 230 candidates nationwide, and thus
was awarded
a joint Algerian/French governments graduate scholarship.
After the first year in France, I earned my DEA degree in Computer Science (a MSc
equivalent), more specifically the DEA on Fundamentals of
Computer Systems and Applications (FSIA) driven by Professor Erol Gelenbe at the University Paris 11 Orsay.
After the DEA, I joined the PhD program of the University Paris 6, Pierre and Marie Curie in 1990. Under the co-supervision of Professor Guy Pujolle at the University and Dr James W. Roberts at France Telecom research labs I worked on the then
hot issues in ATM networks. In end 1993 I defended successfully my PhD
thesis and was awarded my degree of Doctorate of the University Paris 6 in 1994.
In mid-1995 I joined the EEE Department of the Hong Kong University of Science and Technology as a Postdoctoral research associate for a year and a half, then moved to Singapore's Centre for Wireless Communications (now known as I2r, A-Star) a national R&D Centre, where I was a Senior Member of Technical Staff, and Networks group leader, and worked on R&D projects
and the design and development of a cutting edge networking
technology (e.g., prototype wireless ATM NICs with QoS jointly with Ericsson AB, Sweden.)
In fall 2000 I decided to move to academia at the Computer Science Department of the HKUST
where I am an Associate Professor.
My research interests lie primarily in Computer and Communication Networks both wired and wireless.
I am a Senior member of IEEE, and a member of ACM, IEEE ComSoc and
ACM SigComm. I am an Associate Editor of IEEE Communications
Letters and am on the TPC of several major IEEE conferences.
