Short Biography

I am currently a masters student in computer science at Columbia University. Before coming to Columbia, I worked in the United States and China for three years on software application development and project management. My area of interest is computer vision, computer graphcis, machine learning and information retrieval. I will work with Microsoft on Microsoft Expression Encoder after graduation, as a Software Development Engineer II.

Research/Course Projects

• Face Replacement / Columbia University Computer Vision Laboratory / Spring 2008
  The project is the implementation of a face replacement system utilizing various computer vision techniques. It will be applied to automatic face replacement of large amount of images, photo refinement and anonymous identification. The size of the face replacement database is close to 5 million. The development was under the supervision of Dr. Dmitri Bitouk, Neeraj Kumar, Professor Shree Nayar and Professor Peter Belhumeur. I implemented image processor, image database and classifier with C++, OpenCV, Python and mySQL as the core developer.

• DCSearch (www.ccolumbia.info) / Search Engine Technology / Fall 2007
  • Built the crawler and IFI indexer with Perl. Collected and retrieved information from over 10,000 webpages. • Applied Machine Learning and Information Extraction to analyze specification and review information. • Developed an original question answering system for query processing.
