I am a PhD student in Computer Science at University of Southern California. I am very fortunate to be advised by Prof. Haipeng Luo. I received my B.S. from National Taiwan University, double majoring in Electrical Engineering and Mathematics. My research interests lie in theoretical machine learning and algorithmic game theory.
