Background

B.S., 1990, Probability and Statistics, Peking University, P.R. China.
M.S., 1993, Probability and Statistics, Peking University, P.R. China.
M.S., 1999, Computer Science, University of California, Santa Barbara.
Ph.D.,1999, Statistics, University of California, Santa Barbara.

I joined the Department of Bioinformatics and Biostatistics in September 2007 as an Associate Professor. Before that, I was an Assistant Professor at Mississippi State University (tenured and promoted to associate prof in Spring 2007).

Research Interests

My main research area is in probability modeling and statistical inferences in periodic cancer screening. Besides that, I am interested in Bayesian inference, statistical decision theory, time series, smoothing spline, wavelet regression and all kinds of statistical problems in medical research.

Current Projects

a. When to schedule the next mamogram for an asymptomatic woman with her screening history?
b. How to evaluate long-term benefit due to regular cancer screening?

 

Teaching Activities

a. Probability---PHST 661.
b. Mathematical Statistics---PHST 662.
c. Bayesian Inference---PHST 691.
d. Advanced Nonparametric Statistics---PHST 780.
