He received his Bachelor of mathematics and Master of economics from Peking University in Beijing, and his Ph.D. in economics from the London School of Economics and Political Science in 2018. His research focuses on econometric theory, in particular, the nonparametric and semiparametric estimation and inference in the presence of measurement errors. He is also interested in the applications of these tools to empirical problems in policy evaluations. His current research topics include the regression discontinuity design with a mismeasured running variable and the nonparametric additive model with mismeasured covariates.
