I was a member of Srini's Distributed Systems Network Protocols and Applications (DNA)
group, 2000-2005. My research was funded in most part by an
IBM PhD Fellowship for the years 2003-2005. I graduated in Sep 2005.

Here's a brief overview of some key projects I have worked
- Thesis research: Endpoint-Based Routing Strategies for Improving Internet Performance and Resilience
In my thesis research, I adopted a systematic, four-step approach to
the problem of optimizing the performance of well-connected Internet
end-points, such as universities, large enterprises and data
centers. I showed that constrained bottlenecks inside and between
carrier networks in the Internet could limit the performance of such
end-points. I observed that a clever end point-based strategy, called
Multihoming Route Control, can help end-points route around these
bottlenecks, and thereby improve performance. Furthermore, I showed
that the Internet's topology, routing and trends in its growth may
essentially worsen the wide-area congestion in the future. To this
end, I proposed changes to the Internet's topology and routing
protocols to guarantee good future performance. Results from my thesis
work have appeared in SIGCOMM 2003 [paper, abstract], SIGCOMM 2004 [paper, abstract], USENIX 2004 [paper, abstract], PODC 2003 [paper, abstract] and IMC 2003 [paper, abstract]. Also check out these web pages: [Performance bottlenecks] [Multihoming Route Control].
I defended my thesis on 22 June 2005. The final version is now available online.
- Other work:
I have also worked on a variety of other projects, both in CMU and
elsewhere. The topics I have worked on include Wireless Networking,
Game Theory, Security, Measurements, System Design and Implementation,
and Analysis. I will put up a more comprehensive research page in the
near future. For now, here is a brief list:
Teaching at CMU
Mentoring at CMU
I helped mentor
Arvind Kannan's Senior Undergraduate Thesis in
2002-2003. Currently, Srini and I are mentoring Sameer
Moidu's work. Also, I helped guide Jeffrey
Pang's research during 2003-2004.
