About me

Dr Chao Huang is a tenure-track assistant professor at the University of Hong Kong. He is a faculty member of the Institute of Data Science and Department of Computer Science. Before that, he was a research scientist at JD Research America in Silicon Valley. He obtained the Ph.D degree from the Computing Science and Engineering Department at University of Notre Dame in United States.

Current Research Project

Dr Huang, through his research, aims to achieve a long-term goal of developing effective, expressive, efficient and interpretable machine learning solutions, to distill useful knowledge from the complex data and facilitate various underlying applications with across different disciplines. Applications include, web services, recommender systems, smart cities, and computational social science.
