Biography
Professor Liu Ruixuan is an Associate Professor at the Chinese University of Hong Kong (CUHK) Business School. He received his PhD in Economics from University of Washington. His research is in the area of econometrics and data science. His recent works focus on nonparametric Bayesian inference and its applications to econometric models. His research work has been published on Econometrica, Journal of Econometrics, Econometric Theory and Quantitative Economics, etc. He won the 2018 Arnold Zellner Price (jointly with Yanqin Fan) for the best theoretical econometrics paper published by Journal of Econometrics between 2016 and 2017. He is currently an associate editor of Journal of Econometrics and Econometric Reviews.
