About Me:

Welcome! This is my research webpage and lists some of the projects I am involved in and some of the work that I am doing. Contact me in case of any queries!

I completed my PhD from the Computer Science and Engineering Department at the University of California, San Diego in September 2009! 
My advisor was Prof. Rajesh Gupta and I am a member of the Micro Electronic Embedded Systems Lab (MESL) and the Systems and Networking Group @ CSE/UCSD. 

I have also had the privilege to actively collaborate with several stellar researchers from various top research labs, and an awesome set of faculty and graduate students at UCSD!
 
Interests:

My interests lie in the area of Systems and Networking, Embedded Systems, Mobile Computing.
I am particularly interested in building scalable and efficient systems, energy management issues and wireless communication.

Currently I am looking at :

•  Energy-Aware (or Green!) Computing for Laptop and Desktop Computers (Somniloquy)
•  Reducing the Energy Consumption for Wireless Communication in Mobile Devices
  • Leverage multiple heterogeneous wireless interfaces with different radio characteristics 
    such as energy-per-bit, idle power, throughput, range/location effects etc. (CoolSpots, SwitchR)  
  • Use a second lower power radio interface to serve as a paging radio for a high-power radio (On-Demand-Paging) 
• Power Management for a VoIP over WiFi use Scenario for a Smartphone device (Cell2Notify)
• Mitigating the Impact of VoIP traffic over Wi-Fi infrastructure networks (SoftSpeak)   
• Energy Aware Compressed Communication  

Projects:

• Somniloquy (with Microsoft Research, Cambridge and Microsoft Research Redmond)   
• SoftSpeak (with Patrick Verkaik and Alex Snoeren @ CSE/UCSD)
• SwitchR (with Intel Research, Santa Clara)
• Cell2Notify (with Microsoft Research, Redmond)
• CoolSpots (with Intel Research, Santa Clara)
• On Demand Paging (with Curt Schurgers @ ECE/UCSD)
• Smart Vivarium (SV) (with Vincent Rabaud and Serge Belongie)
