Dr. Guobin Shen received the B.S. degree from Harbin University of Engineering, Harbin, China, in 1994, the M.S. degree from Southeast University, Nanjing, China, in 1997, and the Ph.D. degree from Hong Kong University of Science and Technology (HKUST) in 2001, all in Electrical and Electronic Engineering. He is a senior member of IEEE and a member of ACM.

Dr. Shen was a Research Assistant at HKUST from 1997 to 2001. Since then, he has been with Microsoft Research Asia where he is now a lead researcher in the Wireless and Networking Group. His research interests include distributed systems and peer-to-peer networking, mobile computing and systems, wireless sensor networks, video compression and streaming, distributed and parallel computing, and general computing on GPU.

Dr. Shen has published about a dozen journal papers and over thirty conference papers. He has been granted two US patents for his PhD work and filed near twenty patents after joining Microsoft. He has also been very active in contributing services to the communities. He is now a member of multimedia system and applications technical committee (MSATC) of the IEEE Circuits and Systems Society, an associate editor to several journals, a TPC member for many international conferences, and a reviewer for many journals and many conferences.

News

BeepBeep demo ( "A BeepBeep Ranging System on Mobile Phones ") won the Best Runner-up Demo Award at SenSys 2007.

The paper "BeepBeep: A High Accuracy Acoustic Ranging System using COTS Mobile Devices," accepted to ACM SenSys, 2007.

MobiUS demo (a.k.a Lover's Phone) won the Best Demo Award at MobiSys 2007.

MobiUS demo (a.k.a Lover's Phone) was shown to public, mainly Chinese media and press, at Microsoft TechFest 2007 and received wide media coverage from major Chinese web portals including Sina, Sohu, Xinhuanet, Science and Technology Daily, etc. Refer to MobiUS site for some selected links.

The paper "MobiUS: Enable Together-Viewing Video Experience across Two Mobile Devices," accepted by MobiSys 2007.

Research Statement

Previously, I was with Internet Media group at Microsoft Research Asia. I have been working on various video processing and delivery related projects, ranging from efficient MPEG-2 to WMV transcoding, GPU accelerated video encoding and decoding to MPEG-2 transport stream wrapper for WMV bit stream, collaborative peer-to-peer streaming framework for scalable media. Significant results were achieved, including for example, 4~7 real-time transcoding speed for standard definition video, and real-time high definition WMV video playback on Xbox.

After joining Wireless and Networking group in Sept., 2005, I decided to stay more focused. Now I am working on three directions: mobile systems, wireless sensor networks and peer-to-peer networking. I am particular interested in exploring the social connections in building mobile systems. For wireless sensor networks, observing that research on wireless sensor networks getting mature, I am investigating how the wireless sensor network can serve the users by for example making the home/office smarter and interactive. My focus is to build real workable system manifesting the value of wireless sensor network. I am wrapping up my work on peer-to-peer and handing off this area, but this doesn't prevent me to think about it occasionally.
