I got my PhD from Brown University in 2007 under the supervision of Professor Donald McClure and Professor Charles (Chip) Lawrence. My thesis is on image processing and statistical genetics (using hidden Markov models). I spent 7 years at Nanyang Technological University in Singapore, then 2 years at University of New South Wales in Sydney, and start working at the City University of Hong Kong in 2016 as an associate professor. My current research interest include semiparametric regression models, distributed estimation for large data, quantile regression, high-dimensional data analysis, Bayesian computation,
