I am a postdoc with Prof. Hari Balakrishnan, working on problems in Systems and Networking. I am leading the development of an FPGA-based high-throughput and low-latency programmable wireless platform for accelerating innovation in wireless protocols, especially those based on cross-layer designs.
NSDI 2009 paper on mitigating botnets using TPMs accepted.
Powerpoint slides for the two HotNets talks are available. ODS and VWID.
The camera-readies of our HotNets'08 papers are available.
The camera-ready and talk of our MobiCom WiNS-DR 2008 workshop paper are available.
I co-lectured 6.829 (Graduate Computer Networks) with Prof. Hari Balakrishnan and Dr. Bruce Davie in Spring 2008.
Our SIGCOMM 2007 talk slides (PPT) are available.
I won the 3rd prize in the ACM Student Research Competition (SRC) held at PLDI.
Our PLDI 2007 talk slides (PPT) are available.
Our MobiCom 2007 paper is accepted. The camera-ready is available.
Our SIGCOMM 2007 paper is accepted. The camera-ready is available.
Our PLDI 2007 paper is available.
I
am broadly interested in systems and networks research, with a specific
interest in wireless networks. For my Ph.D. thesis, I
worked on
a cool programming system for sensor networks, called Kairos.
It's a simple dialect of C with support for naming, concurrency
and distribution, and is designed to be easily programmable, message
and energy efficient, and reliable. The system involves building a
compiler and
a runtime.
In the recent past, I worked on other
areas that overlap
systems
and networks, such as robustness and privacy issues in 802.11
networks (HotOS
2007), congestion control in sensor networks (SIGCOMM
2006), and database support for query processing in sensor
networks (ICDE 2005).
At
Berkeley and slightly later, I worked on topics such
as analysis of P2P systems (SIGCOMM
2003),
addressing and routing in the Internet (HotNets
2004, SIGCOMM 2001),
and techniques for
constructing highly-available data services (ASPLOS
2000), and scalable and composable Internet services
(SIGOPS European Workshop 2000, Journal
of Computer Networks 2001).

are also generally available upon request.
I work or have recently worked closely with
Prof. Hari Balakrishnan (MIT),
