I am an Assistant Professor in Computer Science Department and Data Science Program at Worcester Polytechnic Institute (WPI). I obtained two Ph.D. degrees, in Computer Science from University of Minnesota, Twin Cities in 2013, and Electrical Engineering from Beijing University of Posts and Telecommunications in 2009, respectively. I am interested in analyzing, understanding, and making sense of big data generated from various complex networks in many contexts, including management and computing with urban network data, smart cities, and data-driven cyber-physical systems (CPS). I am a senior member of IEEE and a member of ACM.

Openings I am looking for self-motivated PhD students and visiting scholars to work with me on the exiciting area of urban network analysis. I'm particularly interested in candidates with background in big data analytics, data mining, machine learning, and strong programming skill. Please send me a short email with your C.V. and anything you believe relevant! For PhD program applicants, here is the admission page at WPI.
