Research

    Dr. Liqun Wang's research is mainly concerned with theory and methodology of complex data analysis, statistical computation, applied probability, and system identification. His current research includes data assimilation and ensemble Kalman filter; estimation in nonlinear models with errors-in-variables; inference in longitudinal and panel data models; boundary crossing probabilities (first passage time distributions) for diffusion processes; and Monte Carlo methods for statistical computation and numerical optimization. He is also interested in biostatistics, econometrics, and engineering applications.
