Education and Experience

    Liqun Wang received his Bachelor degree in mathematics from Northern Jiaotong University, Master degree in statistics from Beijing Normal University, and Doctoral degree in statistics and econometrics from Vienna University of Technology. He also received a Postgraduate Diploma in mathematical and computer sciences from Vienna Institute for Advanced Studies. He was a post-doctoral research fellow at Universities of Hannover and Dortmund, an assistant professor at University of Basel, and a visiting scholar at University of Southern California, University of California at Berkeley, and University of Toronto.

Research Interests

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