Gengsheng Qin

Gengsheng (Jeff) Qin is a Professor of Statistics in the Department of Mathematics and Statistics at Georgia State University (GSU), part of the College of Arts & Sciences. He holds a PhD in Statistics from the Hong Kong University of Science and Technology (1999), and has been at GSU since 2001, progressing from Assistant to Associate Professor, and then full Professor in 2013. His research focuses on statistical methods in diagnostic medicine, survival analysis, bootstrap and empirical likelihood techniques, nonparametric and semi-parametric regression, and applications of empirical processes in statistics. He has also contributed to discrete data analysis, Edgeworth expansion, and time series modeling.

Education includes a B.S. in Mathematics (Lanzhou University, 1983), M.S. in Statistics (Sichuan University, 1992), and PhD in Statistics (HKUST, 1999). Prior to GSU, he held faculty positions at Sichuan University, China, from 1983 to 2001. His teaching spans courses like Biostatistics, Mathematical Statistics, and Survival Analysis.

Recent work emphasizes statistical methodologies for medical diagnostics, including ROC analysis, verification bias correction, and cost regression models. His articles often integrate empirical likelihood techniques with real-world applications in healthcare and biostatistics. A notable focus is developing confidence intervals and inference methods for medical cost data and diagnostic accuracy metrics.
