Research Interests

Liqun Wang's research is mainly in the areas of applied probability and statistical theory and methodology for complex data analysis. His current research topics include boundary crossing probability (first passage time) for diffusion processes, identification and estimation in nonlinear measurement error models and in longitudinal data models with missing data, high-dimensional variable selection and data assimilation, and Monte Carlo simulation methods in statistical computation and optimization. Liqun is also interested in biostatistics, econometrics, as well as statistical applications in engineering optimization, environmental, medical and health sciences.
