Dr. Joy Ying Zhang is an assistant research professor in Mobility Research Center at Carnegie Mellon University Silicon Valley. He received his Ph.D. from Language Technologies Institute of Carnegie Mellon University.
Most of his research centers around applying statistical learning on natural language processing problems, in particular, statistical machine translation systems. He has developed the Pandora translation system, a full-scale two-way phrase-based statistical machine translation engine for mobile devices. His current research interests include applying statistical learning methods on mobile applications for user behavior modeling and behavior-aware mobile computing including indoor positioning, geo-trace modeling, mobile lifelog.
