Biography

Born in China, he pursued higher education at Zhejiang University before moving to the United States for doctoral studies. His academic journey led him to a prominent career in American academia, where he has mentored numerous graduate students and postdoctoral researchers. Throughout his career, he has maintained active collaborations with mathematicians and scientists at institutions like Vanderbilt University and Oak Ridge National Laboratory, contributing to the international mathematical community.

Education and career

He completed his undergraduate studies at Zhejiang University in China. He then earned his Ph.D. in mathematics from Texas A&M University under the supervision of renowned approximation theorist Larry L. Schumaker. Following his doctorate, he held a postdoctoral position and subsequently joined the faculty of the University of Georgia, where he advanced to the rank of full professor. He has also held visiting positions at prestigious institutions such as the University of Texas at Austin and the Chinese Academy of Sciences.

Research and contributions

His research is centered on multivariate approximation theory, with a deep focus on spline functions over arbitrary triangulations and their applications. He has developed important theoretical results concerning the smoothness and approximation order of bivariate spline spaces, which are critical for finite element analysis. His work on wavelets and frame theory has provided new tools for signal processing and image compression. Furthermore, he has published extensively on radial basis function interpolation and geometric modeling, contributing algorithms used in computer-aided design software and scientific visualization.

Awards and honors

In recognition of his contributions to mathematical sciences, he was elected a Fellow of the American Mathematical Society in 2012. His research has been supported by grants from the National Science Foundation and the Air Force Office of Scientific Research. He has also been honored with an invited speaker position at the International Congress on Industrial and Applied Mathematics and has served on the editorial boards of several journals, including the Journal of Approximation Theory.

Selected publications

His scholarly output includes the influential monograph "Spline Functions on Triangulations" published by Cambridge University Press. Key research papers include works on multivariate splines in the SIAM Journal on Numerical Analysis, studies of wavelet frames in the Journal of Fourier Analysis and Applications, and articles on Hermite interpolation in the journal Advances in Computational Mathematics. He has also co-authored texts on practical mathematical analysis used in graduate instruction.
