Research

Topic-wise, one of my recurring interests is on the analysis and synthesis of repetitive phenomena such as textures, samples, noises, structures, motions, and interactions. These can involve various fields including computer graphics, parallel computing, and human computer interaction. In fact, since computer science is about repetitive computations, I have excuses to work on whatever I like. ☺

Methodology-wise, I am mainly interested in developing fundamental algorithms that span diverse phenomena driven by practical applications, especially on the human side of computation such as graphics and HCI.

Note: due to obvious reasons I cannot release the code for almost all projects I did with Microsoft. If the code is available, I will put it online here. I am afraid I do not have time to answer every email regarding source codes.
