     I am a PhD candidate in the Department of Computer Science and Engineering at The Ohio State University. I work in the Dependable Distributed Network Systems lab led by Dr. Anish Arora. My primary research interests lie in the area of secure and reliable distributed systems with a special emphasis on wireless sensor network systems. I have also been involved in the design and maintennance of a large scale sensor testbed, Kansei, and a mobile sensor network testbed inside the Dreese building to facilitate testing of mobility centric applications.
     In 2008 summer, I was doing an internship at Google Mountain View in the Android team, working on an open source project Android .

Recent experience in systems development

    (i) Implemented a J2ME framework (with hack) on the Motorola E680i/ROKR phones. This framework enables reliable communications between Linux processes and attached Intel PSI motes. It allows the phones to communicate with each other through 802.15.4 network via the PSI motes. This framework is now being used in our campus-wide mobile testbed PeopleNet at OSU

    (ii) Ported TinyOS to the Intel PSI (Phone System Interface) motes. Each PSI mote is equipped with a MSP430 board and a CC2420 radio (IEEE 802.15.4 compatible). It can be attached to Motorola E680i/ROKR phones. I de- signed and developed a platform which supports TinyOS programs running on the PSI motes. This platform has been contributed to the TinyOS community, and has been used by many parties around world (e.g. Motorola Research and Cornell). The source code is available at http://tinyos.cvs.sourceforge.net/tinyos/tinyos-2.x-contrib/osu/

    (iii) Implemented a reliable protocol stack which enables communication between the phone and the PSI motes. This protocol is used in various mobile projects in the PeopleNet at OSU
