Background
Postdoctoral fellow (2015) Bioinformatics and Biostatistics, Emory University.
Ph.D. (2013) Mathematical Science, Clemson University.
B.S. (2006) Mathematics and Applied Mathematics, Nanjing University, China
I joined the Department of Bioinformatics and Biostatistics in Fall of 2015.
Research Interests
My primary research interests are high dimensional data analysis, semiparametric and nonparametric models, varying effects survival analysis, personalized treatments, tree-based learning methods, and statistical applications in epidemiology and biomedical sciences.
