Background

I received the B.Eng. degree with first class honors from The University of Manchester, Manchester, U.K., and the Ph.D. degree from The University of Edinburgh, Edinburgh, U.K., both in electronics and electrical engineering, in 2000 and 2003, respectively.

From January 2004 to September 2005, I was with the Communication and Network Laboratory, Samsung Advanced Institute of Technology (SAIT), Suwon, South Korea. Since October 2005, I have been with the Wireless Access Laboratory, DOCOMO Communications Laboratories USA, Palo Alto, California.

I have done research in the areas of channel parameter estimations, MIMO propagation channel measurements, statistical channel modeling, UWB systems, relaying and cooperative communications. My current research interests include 4G cellular systems, ranging and positioning techniques, wireless personal area network and dynamic spectrum access. I am an active participant and contributor in the IEEE 802.15, IEEE 802.16, ITU-R Working Party 8F (WP8F) and WP5D standardization activities. I have co-authored two book chapters and published more than 80 international journals, conference papers and international standard contributions.

I received the Joseph Higham Prize and the GEC-Marconi Prize from The University of Manchester in 2000 for academic excellence and outstanding performance. I also awarded the IEE Prize and the IEE Vodafone Research Scholarship by the Institution of Electrical Engineers (IEE) in 1999 and 2001, respectively, the Richard Brown Scholarship from The University of Edinburgh in 2002, the IEEE International Conference on Ultra-Wideband (ICUWB) Best Paper Award and the DoCoMo USA Labs President Award in 2006, as well as the URSI Young Scientist Award and the DOCOMO USA Labs President Award in 2008. I was honored with The Outstanding Young Malaysian Award 2006 (the most prestigious achievement award for people under age 40 in Malaysia) by Junior Chamber International (JCI) and Ministry of Youth and Sports, Malaysia under the category “Scientific and Technological Development”.

Currently, I serve as an Editor for the IEEE Transactions on Wireless Communications and the EURASIP Journal on Wireless Communications and Networking (JWCN). I have served as the Lead Guest-Editor for the Special Issue on “Millimeter Wave Wireless Communication Systems” in the EURASIP JWCN and the Guest Editor for the Special Issue on “Cooperative Localization in Wireless Ad hoc and Sensor Networks” in the EURASIP Journal on Applied Signal Processing. I have also served on the Technical Program Committee (TPC) of various international conferences, the TPC Co-Chair for the Broadband Wireless Access Symposium of the IEEE International Conference on Computer Networks and Communications (ICCCN) 2007 in Honolulu, HI, USA, the TPC Co-Chair for the Wireless Communications Symposium of the IEEE International Conference on Communications (ICC) 2008 in Beijing, China, the Publicity Co-Chair for the IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC) 2008 in Cannes, French Riviera, France, the Sponsorship Chair for the International Conference on Cognitive Radio Oriented Wireless Networks and Communications (CrownCom) 2008 in Singapore, and the Tutorial Chair for the IEEE ICCCN 2009 in San Francisco, CA, USA. I was the Chair for the DG-EVAL Channel Model standardization group within the ITU-R WP8F/WP5D for IMT systems.
