Tze Leung Lai is the Ray Lyman Wilbur Professor and Professor of Statistics at Stanford University. He received the COPSS Presidents' Award in 1983. He has published extensively on sequential statistical analysis and a wide range of applications in the biomedical sciences, engineering, and finance.Haipeng Xing is a Professor of Applied Mathematics and Statistics at State University of New York, Stony Brook. His research interests include sequential statistical methods and its applications, econometrics, quantitative finance, and recursive methods in macroeconomics.

"Overall, Data Science and Risk Analytics in Finance and Insurance is a well-executed and substantial book. It combines strong theoretical foundations with practical relevance and computational techniques. The breadth of topics covered, the clarity of exposition and the integration of classical and contemporary approaches make this work a significant contribution to the literature. The book deserves a wide readership among students, researchers and practitioners interested in quantitative finance and insurance analytics. It is likely to serve as an important reference work and a useful graduate-level textbook in the years ahead."-Svetlozar Rachev in the International Statistical Review, 2026.
