ResearchMy primary research interests are in Sensing and Mobile Computing. Specifically, we are focusing on building ultra energy- and channel-efficient dense sensor systems. The key to achieving the efficiency is through the rethinking of the network architecture as well as the collision handling in a dense sensor system. 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 also started looking at techniques to capture the contextual information around human conversations, such as the number of speakers in a conversation, through smartphones. These techniques can find applications in many domains, and we are currently targeting at the following domains: smart building, 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 seamlessly support mobility, content retrieval, context-based communications that will be prevalent in tomorrow's Internet.
TeachingIn Spring 2014, I am teaching 14:332:331 Assembly Language and 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 14:332:331 are held on Tuesdays 10:00 -11:00 AM, in the lounge area on the 5th floor of Core (outside the elevator).
StudentsCurrently I am supervising the following Ph.D. students: Tingting Sun, Chenren Xu, Feixiong Zhang, and Sugang Li. I am also working with the following Master students: Jakub Kolodziejski and Zhenhua Jia.
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.
