He is a member of CITIC.

His research focuses on the fields of nonparametric inference, resampling methods, survival analysis, empirical likelihood, functional data analysis, big data statistical analysis, and statistical methods in epidemiology, genomics, neuroscience, weed science, oncology and credit risk. He is the author of more than 250 publications collected in Google Scholar. He supervised fifteen doctoral theses. He was editor or co-editor-in-chief of the journals Journal of Nonparametric Statistics (2019-2021), Computational Statistics (2016-2018) and TEST (2009-2012) and also associate editor of them and of Computational Statistics & Data Analysis.

He is an Elected Member of the International Statistical Institute and was named Fellow of the Institute of Mathematical Statistics in 2022.
