Department of Statistics

Student working at a desk


Our department excels at collaborative research between faculty, students and other universities. 

Our research activities are organized into eight themes, each with a leader and several members from the faculty and graduate students. The research themes are:


Survival analysis and reliability

Semiparametric and nonparametric inference in survival analysis and reliability

Primary Theme: Karl Gregory, Tim Hanson, Edsel Peña , Lianming Wang, Jim Lynch (emeritus)

Secondary Theme: Xiaoyan Lin, Xianzheng Huang, Yen-yi Ho


Latent variable models

Measurement error models, group testing, robustness, clustering, inter-rater agreement, educational measurement, item response theory, longitudinal data analysis

Primary Theme: Brian Habing, Xianzheng Huang, Josh Tebbs

Secondary Theme: Don Edwards, Tim Hanson, David Hitchcock, Xiaoyan Lin, Dewei Wang, Lianming Wang


Semiparametric methods

Dimension reduction, case-control data analysis, finite mixture models

Primary Theme: John Grego

Secondary Theme: Tim Hanson, Yen-yi Ho, Dewei Wang, Jim Lynch


Bayesian statistics and Bayesian nonparametrics
