Research Highlights

I am generally interested in ICT-related policy and management issues. In particular, I am using a double-edged sword, namely econometrics and machine learning techniques to “hack” the complex data-driven problems. I have been fortunate to work with my advisors on a myriad of applications, such as social network analysis, consumer behavior, telecom policy, behavioral finance and innovation management.
