My research areas include machine learning, intelligent systems, digital image processing, and algorithm efficiency. Currently I am applying the technique of partially observable Markov decision process (POMDP), along with reinforcement learning, to building intelligent tutoring systems (ITSs).

My work is aimed at developing new techniques/algorithms for handling uncertainties, improving performance, and reducing computing costs.
