I am a Ph.D. candidate in the Computer Science Department at Carnegie Mellon University, advised by Professor Takeo Kanade. In 1999~2002, I spent three years as an associate researcher at Microsoft Research Asia. I received a Master degree in computer science in 1999 from Peking University.

Research objectives

My main research interest is in developing robust and efficient algorithms for object recognition. A common thread in my research has been the focus on reasoning the shape of visual objects from noisy, real-world images, where the uncertainties over image appearance and imaging conditions are prevalent. The ability to resolving such uncertainties and reliably identifying object structures is the major difference between machine vision and human vision systems. My approach is primarily a Bayes one, involving designing hierarchical models that represent visual shapes, and developing inference algorithms to retrieve them from images.
