Heather Zheng
I am an associate professor at 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 lead the
LINK Lab, part of the Next
Generation Networking Group.
I was one of the
MIT Technology Reivew'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); I am a fellow of the
World Technology Network. More
details can be found from my Curriculum
Vitae.
I am looking for 1-2 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, 1--2 representative publications
(if any) with a subject line "UCSB Applicant.''
My Research
My general research area includes wireless networking and systems,
mobile computing and multimedia computing. I am also interested in
security, distributed systems and social networks. My current research is on cognitive radios
&
networking, dynamic spectrum sharing and auctions, with a particular
focus on improving network reliability and robustness. Detailed
information can be found from the Research
Overview
as well as the List of Publications. Please also check out LINK Lab's webpage for most
recent project/publication information.
I recently started to work on models of social
networks, collaborating with Prof. Ben Y.
Zhao's group, and our first result appeared in WWW 2010.

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.
