About Me:
I am an assistant professor in the computer engineering group at the Ming Hsieh Department of Electrical Engineering at the University of Southern California. Prior to my teaching career, I worked in industrial research labs for 6 years; first at the Intel Microprocessor Research Labs as a senior researcher for five years and then at the Nokia Research Center Palo Alto as a visiting research faculty for eight months. At Nokia my research focused on mobile platform services. At Intel my research focused on computer systems architecture spanning the entire computer system design space; from new silicon technologies at that hardware level to systems software analysis of server workloads. The common theme in all my research work is that I chose an experimental and quantitative approach for evaluating my ideas. As such I built mobile application prototypes at Nokia to increase information relevance using location information. At Intel I have done extensive full system simulations, built physical system prototypes and experimented with existing SMP systems to judge the merit of my computer systems architecture ideas.

- Several recently accepted papers at workshops and other multi-disciplinary conferences are listed under my Research tab.
- Our group received three NSF awards in 2008. Details of these awards can be found on NSF website.
- The application of mobile devices in health care is an area that we started exploring recently. Our team received a coveted NIH supplemental grant for two years to build a complete mobile end-to-end system, called KNOWME network, that allows doctors to monitor the behavior of pediatric obesity subjects. We are now in the process of developing software in preparation for the field trials. We published several papers on this research. Please see the health related publications under my Research tab. This work is also funded by Qualcomm and Nokia.
My research in PRESS
- Course on Mobile Programming: The EE579 course I co-teach with Prof. Bhaskar Krishnamachari was awarded Steven's Institute's Innovation Inside award. Here is the Steven's new article. Here is what Daily Trojan has to say.
- Mobile Traffic Sensing: I co-developed a traffic monitoring system that uses GPS enabled cell phones to sense traffic conditions in real time. A large scale experiment was performed using this research platform in the San Francisco bay area on Feb 8th 2007. This research platform uses a novel concept of Virtual Trip Lines that I co-developed while working at Nokia prior to joining USC and I continue to collaborate on this project now with Nokia and UC Berkeley. The experiment was widely covered in many leading news media. Here is a select list:
