I am a research scientist in Prof. Bryan Ford's group, working on problems in Systems and Networking.
Our Hotstorage'12 paper on non-linear compression is accepted.

interest in wireless networks. For my Ph.D. thesis, I
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
In the recent past, I worked on other
areas that overlap
and networks, such as robustness and privacy issues in 802.11
2007), congestion control in sensor networks (SIGCOMM
2006), and database support for query processing in sensor
networks (ICDE 2005).
Berkeley and slightly later, I worked on topics such
as analysis of P2P systems (SIGCOMM
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).

The latest Kairos compiler and
runtime tarball is here. I don't currently have the time to support this software, but you can use it any way you want to.
Code and data sets for other papers I've written
are also generally available upon request.
I work or have recently worked closely with
Prof. Hari Balakrishnan (MIT),
Govindan (USC) and Prof. Todd
Millstein (UCLA). I also collaborate with Prof. Arvind (MIT), Prof. Robert Morris (MIT), Prof. Eric Brewer (Berkeley), Prof. David Wetherall
(UW), and Prof. Srini
Seshan (CMU). In the recent past, I had the privilege to work with
many other wonderful researchers and grad students, and they can be found on the pubs
