Research

My research spans across information systems, finance, and organization science. Web 3.0-related topics are of particular interest, including blockchain, decentralization, and token-based economics, as well as Web 2.0 topics such as digital and mobile platforms and social networks. 

Methodologies such as applied econometrics, statistical and economic analysis, and social network analysis are common in my research. I am also interested in analytical modeling for operations management research.
