OBJECTIVE

Seeking a challenging summer internship position in the area of computer networks and operating system.
RESEARCH INTERESTS
Computer networks, distributed systems and applied security.

I am interested in building scalable, flexible and secure network infrastructure. The project I have been involved with, the Grid network, is about building a large cooperative network among the mobile devices themselves. My work is focused on routing and protocol performance analysis.

My interests in distributed systems arise from our current work towards actual deployment of the Grid system. I feel traditionally operating systems design is ill-suited for small network devices. The problems that I would like to work on are: How to make OS small, efficient, and less power hungry? How to design a peer-to-peer system that would make sharing/searching files easy? How to secure our systems and communications without sacrificing convenience and performance?

EDUCATION
EXPERIENCES
Research Assistant (Parallel and Distributed Operating Systems Group, LCS/MIT, 1999-now)
Grid Ad hoc Routing Protocol
I helped design and simulate the Grid Ad hoc Routing Protocol. Existing ad hoc routing protocols have problems scaling to large networks because of the need to distribute global topology information. Grid uses geographic forwarding, which only needs local neighborhood information when routing packets. We designed the scalable distributed location service protocol, the Grid Location Service (GLS), which maintains geographic location information for each node and is scalable to large networks.

Capacity Analysis of Large Ad hoc networks
Existing simulations on ad hoc routing protocol performance show surprisingly low data capacity. We showed that the capacity available to each node in an ad hoc network depends critically on the communication pattern of the nodes. We also proposed several possible communication patterns that can scale to large networks.

Research Assistant (Mobile Computing Lab, National University of Singapore, 1998-1999)

I designed the Cluster-based Ad hoc Routing Protocol and presented it to the IETF MANET (Mobile Ad Hoc Network) group. I was also actively involved in the Mobile IP group and was responsible for field testing the lab's Mobile IP implementation.

Research Assistant (Center for Internet Research, National University of Singapore,1999)

I designed and implemented the Internationalized Domain Name System (iDNS) for IPv6 and tested the system on an IPv6 testbed with modified IPv6-compatible BIND. The iDNS project leads to the formation of i-DNS.net International Inc. which successfully launched international domain name registeration services in various countries.

Teaching Assistant (MIT/EECS, Course 6.894: Distributed Operating Systems, Fall 2000)

I helped design and grade labs. I was also in charge of maintaining course materials online and answered students' questions.

Teaching Assistant (School of Computing, National University of Singapore, 1998)

I taught senior level computer network and operating system classes. My duties include leading recitations and designing problem sets and final projects.
