New! I am on the job market for Fall 2010 and looking for an academic/research position. My job materials (pdf format) can be found here: CV, research statement, and teaching statement.

 I am currently a Ph.D. candidate in the Department of Computer Science at the University of Illinois, Urbana Champaign and a Siebel Scholar. I work with Prof. Tarek Abdelzaher on developing an infrastructure toolset for human centric sensing. I obtained my Masters degree at the University of Illinois, Urbana-Champaign in Computer Science in Fall 2006. I was a Masters student at the Department of Computer Science of University of Virginia from Fall 2003-Fall 2005 and moved to UIUC in Fall 2005. I did my undergraduate from Indian Institute of Technology - Madras in Computer Science and Engineering.

Research (top)
 My research interests broadly lie in the area of Cyber physical systems, Wireless sensor networks, Wireless Networks, and Data mining. I work with Prof. Tarek Abdelzaher. The major research projects that I am working/worked on are summarized below:
   
1.  GreenGPS
      GreenGPS is a novel service that computes fuel-efficient routes for vehicles between arbitrary end-points. Similar to how Google maps or MapQuest compute the shortest or the fastest routes, GreenGPS finds the "green" route between two end-points that consumes the least amount of fuel. This is accomplished by expoliting the vehicular sensor measurements available through the OBD-II interface on the car. More information about GreenGPS and the service can be found here.

2.  PoolView: Privacy in Cyber Physical Systems
     PoolView aims to develop the infrastructure, algorithms, and sample applications that will be representative of the next generation sensor web. We envision that future software will collect sensor data from devices that people own in their everyday lives in an automated manner and analyze this data to meet human decision needs. For example, our traffic analyzer application collects GPS data from individual users in a privacy preserving manner and provides traffic summaries for a given city. The GreenGPS application computes the fuel efficient routes from the OBD-II sensor data collected from people driving their cars. We built the infrastructure that enables people to share the sensor data they collect within a community and addressed research problems such as sharing the data in a privacy preserving manner.

3.  Smart Attire
      Smart attire is the next generation of clothing that will embed sensing and computing power in the clothing of people to improve the lifestyle of our society. We envision that such clothing will provide  the user with various services, which we classify into four different categories:
        1. Elderly individual's health care
        2. Safety of people
        3. Personal and medical
        4. Entertainment

     Towards this vision, we have developed a working prototype of a smart jacket, with sensing devices (MicaZ motes) embedded in it, that records the daily activities of the person using it in the form of accelerometer data, and GPS data. These data collected are uploaded to a PC through a mote attached to it, opportunistically. Such data are then interpreted to identify activity and location information of the user. We are currently looking at mining for "interesting" patterns in long term data, that we are collecting as part of our ongoing research. More information about this project can be found by following this link.

4.  AlarmNet: Assisted-Living And Residential Monitoring Network
     AlarmNet is a project that I am collaborating on with the Department of Computer Science, University of Virginia. This project aims to develop an architecture for intelligent health care using wireless sensor networks. It is targeted at assisted-living facilities and nursing homes and aims to improve the lives of elderly individuals by making them more independent. Sensing and computing devices are unobtrusively deployed in health care facilities, which continously monitor the individuals' health and generate reports to the authorized care providers. Currently, we have a system deployed that mimics a typical health care facility. This system has several components, such as the bed network, motion sensors, body network, human interfaces, and so on. More information on this project can be obtained by visiting the following webpage.   

5.  Seda: Improving Throughput of Wireless Sensor Networks
     Wireless sensor networks have suffered from low throughput caused by the high error rates (due to the low-end radios) and small sized packets (TinyOS, the default operating system for sensor networks, uses a 29 byte payload with a 16 byte header). We developed Seda, a streaming datalink layer that improves the throughput of sensor networks by decoupling the unit of communication (frame) from the unit of error recovery. Seda introduces the unit of error recovery as a block, which is significantly smaller than a frame to reduce the overhead of error recovery, which is the primary cause for decreased throughput. Seda is currently implemented in TinyOS and is available at the following page.
