I am a 2nd year Ph.D. student in the Video Retrieval Group (VIREO) at City University of Hong Kong, where I work under advisor Dr. Chong-Wah Ngo. Currently, I am working in the Digital Video and Multimedia Lab (DVMM) at Columbia University as a visiting student, under the direction of Prof. Shih-Fu Chang.

My research interests include multimedia information retrieval and video content analysis, with strong connections to computer vision and pattern recognition. I am currently investigating techniques for automatically indexing large-scale multimedia collections.
