I am a researcher and the manager of the Visual Computing Group http://research.microsoft.com/en-us/groups/vc/ at Microsoft Research Asia, Beijing, China. I am interested in studying mathematical principles behind the processing and understanding of visual data such as images and videos. In particular, I recently work on high-dimensional data clustering and classification, compression-based image segmentation, robust face recognition via sparse representation, and error correction for high-dimensional signals and matrices.

Before joining MSR Asia in January 2009, I has been a tenured associate professor at the University of Illinois at Urbana-Champaign since 2000. You may find more information about my research and publications from my website at the university: http://yima.csl.illinois.edu
