Topic-wise, I am interested in the analysis and synthesis of phenomena that repeat themselves, such as textures, samples, signals, structures, motions, and interactions across various scientific and engineering disciplines. In fact, since computer science is about repetitive computation, I can justify working on whatever I like. ☺

Methodology-wise, I focus on developing fundamental algorithms with diverse applications, especially on the human-facing side such as graphics and HCI.
