Computer Science University of California, Santa barbara
I am a Professor at the Department of Computer Science. I received my PhD in Electrical and Computer Engineering from University of Maryland, College Park in 1999. I joined UCSB after spending 6 years in industry labs (Bell-Labs, NJ and Microsoft Research Asia). At UCSB, I co-direct the SAND Lab (Systems, Algorithms, Networking and Data) together with Prof. Ben Y. Zhao.
I was selected as one of the
MIT Technology Review's TR
35 (2005) for my work on Cognitive Radios; my work was
featured by MIT Technology Review as one of the
10 Emerging Technologies (2006); and I am a fellow of the
World Technology Network. More
details can be found in my Curriculum
I am looking for talented and self-motivated graduate students on wireless networking or social networks. Prospective students should first read the Admission FAQ page, and then email me your resume with a subject line of "UCSB Applicant."
My general research areas include wireless networking and systems,
mobile and social computing. My current research is on mmWave networking,
wireless data centers, cognitive radios
and dynamic spectrum access, and social networking. Please see SAND Lab Page for specific projects.
One of our current projects is to develop outdoor 60GHz picocells aiming at delivering 1000x more bandwidth to celluar users. This project is supported by NSF and Google. Our first result appeared at MobiCom'14.
Another project, also funded by NSF, is on crowdsourcing enabled spectrum monitoring and enforcement. Our initial result appeared at HotWireless'14.
Past Research: My research spreads across multiple layers. At Microsoft Research Asia, I initiated and led the Nautilus project on Open Spectrum Systems; At Wireless Research Lab, Bell-Labs, I worked on Radio Resource Allocation for Broadband Wireless Networks including MIMO/BLAST, Network Scheduling and TCP, and Base Station Router. My Ph.D. thesis research at Univ. of Maryland, College Park was on multimedia communications, a cross layer design framework to provide resource-efficient multimedia delivery over noisy networks. Here are the links to some of my collection of past projects.
