I focus on areas emerged from the interface between Computer Science and Economics, more specifically on computational game theory and its applications. I am interested in game-theoretic problems in reputation and ranking as well as those in the context of networks and market mechanisms. I also conduct experimental research online for studying game-theoretic interactions among human subjects. I am co-supervised by Prof. Luke Ong and Prof. John Quah from Department of Computer Science and Department of Economics respectively. In addition to my doctoral work, I was a Research Assistant at Centre for Experimental Social Sciences, where I designed, implemented and conducted lab-based behavioral experiments for research in Economics.
