Dehao YU

Profile:

Elected Academician of the International Eurasian Academy of Sciences in 2014, Professor Dehao Yu is a distinguished Chinese computational mathematician whose research and professional work have focused on finite element and boundary element methods and the numerical solution of partial differential equations, particularly in unbounded domains. Born in April 1945 in Yin County, Ningbo, Zhejiang Province, he studied Applied Mathematics at the University of Science and Technology of China from 1962 to 1967. After working in agricultural and industrial settings for a decade, he entered the Computing Centre of the Chinese Academy of Sciences in 1978 and became a graduate student of Academician Feng Kang, receiving his M.S. in 1981 and Ph.D. in 1984. He subsequently conducted research at the University of Maryland in the United States and the University of Stuttgart in Germany as a Humboldt Research Fellow. Returning to China in 1988, he was appointed Research Professor in 1990 and Doctoral Supervisor in 1993. He served as Deputy Director of the Institute of Computational Mathematics and Scientific/Engineering Computing, CAS, from 1995 to 2003, Vice President of the Chinese Society of Computational Mathematics from 2002 to 2006, and a member of the expert group and Deputy Chief Scientist of the 973 Programme project on Large-Scale Scientific Computing. He is currently Research Professor and Doctoral Supervisor at the Academy of Mathematics and Systems Science, CAS. His honours include a First Prize of the Chinese Academy of Sciences Natural Science Award, recognition as a Doctoral Degree Holder with Outstanding Contributions and a National Middle-Aged and Young Expert with Outstanding Contributions, and the State Council Special Allowance.

Professor Yu’s research has centred on natural boundary reduction, boundary element methods, and numerical methods for partial differential equations in unbounded domains. Under the guidance of Professor Feng Kang, he developed the theory of natural boundary reduction and established the natural boundary element method, including natural integral equations and the associated analysis of their mathematical properties. His work addressed key numerical difficulties in boundary integral equations, including hypersingular kernels, and led to methods for coupling finite and boundary elements and for constructing artificial boundary conditions for problems in unbounded domains. He subsequently developed domain-decomposition algorithms based on natural boundary reduction and contributed to error estimation and adaptive methods for finite and boundary element calculations. His research also extended boundary element techniques to variational inequalities and ill-posed problems. His monographs The Mathematical Theory of Natural Boundary Element Methods and Natural Boundary Integral Method and Its Applications have contributed to the development and dissemination of natural boundary methods in computational mathematics. Together with Professor Houde Han, he received a Second Prize of the National Natural Science Award in 2008 for work on artificial boundary methods and numerical solutions of partial differential equations. He has published more than 120 papers and supervised numerous doctoral students and postdoctoral researchers. Through sustained research, methodological development, and academic mentorship, Professor Yu has contributed to the development of computational mathematics in China and to advances in boundary element theory and numerical methods for partial differential equations.
