BioI joined the Electrical and Computer Engineering department of Rutgers University as an Assistant Professor in 2002. In 2008, I was promoted to Associate Professor with tenure. I am also a member of the Wireless Information Networking Laboratory (Winlab). During March-July 2009, I was a visiting scientist at Nokia Research Center Beijing. Prior to joining Rutgers, I completed my Ph.D. in Computer Science and Engineering at Penn State University in 2002, and my B.S. in Computer Science at University of Science and Technology of China in 1997.
I am the recipient of the NSF CAREER award. I am currently an Associate Editor for IEEE Transactions on Mobile Computing and IEEE Transactions on Services Computing. I have served on TPC for many conferences, including Infocom, ICDCS, DSN, IPSN, etc.
Research [Publications][CV]My primary research interest is developing efficient sensing and mobile systems, through rethinking network architecture and communication protocols. Currently, I am building large single-hop sensor networks using transmit-only sensors, which promises to significantly cut down power consumption and improve channel utilization. This technology has led to the launch of Owl Platform. In addition, I am developing unobtrusive techniques to extract important contextual information from people's everyday life. For example, we can track people's indoor locations without having them wear any devices; we can infer the number of people a person speaks to everyday without compromising their privacy. I am now applying these techniques in domains including smart building, aging in place, and youth psychology.
I am also involved in developing the global name resolution system (GNRS) for the MobilityFirst Future Internet Architecture at WINLAB. GNRS can seamlessly support internet access (with latencies lower than 100ms) for billions of mobile devices.
In the past, I have worked on a variety of projects on sensor networks and distributed computing, including item-level asset-tracking using active RFID, congestion alleviation through resource control in sensor networks, sensor network jamming resistency, source location privacy in sensor networks; cache and forward Internet architecture, and CPU scheduling for clusters and grids.
