ResearchMy main research interests are in Sensing and Mobile Computing. We are working on building ultra energy- and channel-efficient dense sensor systems. The key to achieving the efficiency is through rethinking the network architecture as well as how collisions can be handled in a dense sensor network. In addition, we are also developing passive radio frequency-based localization techniques that can accurately estimate the number, location and trajectory of people in an indoor space. Recently, we have developed techniques to capture the contextual information about human conversations, such as the number of speakers, through smartphones. We are applying these techniques to the domain of smart health, aging in place, and youth psychology.
Also, I have always been interested in the area of Distributed Computing. Currently, we are working on the global name resolution system (GNRS) for the MobilityFirst Future Internet Architecture at Winlab. GNRS can support mobility, content retrieval, context-based communications that will be prevalent in tomorrow's Internet.
TeachingIn Fall 2013, I am teaching 14:332:423 Computer and Communication Networks and 16:332:563 Computer Architecture. For students who are taking these classes, please visit Sakai for more detailed information. If you wish to be added to Sakai, please email me.
Office hours for 14:332:423 are held on Tuesdays 9-10AM, in the lounge area on the 5th floor of Core (outside the elevator). Office hours for 16:332:563 are by appointment only.
StudentsCurrent I am supervising the following Ph.D. students: Ben Firner, Tingting Sun, Chenren Xu, and Feixiong Zhang. I am also working with the following Master students: Sugang Li, and Jakub Kolodziejski.
We are constantly looking for motivated students who are not afraid of taking risks, doing the hard work, or at least deploying sensors in the wild. I especially encourage students from the underrepresented group to apply.
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.
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.
