     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 did an internship at Google Mountain View in the Android team, working on an open source project Android .
