معرفی
Lloyd Nicholas Trefethen is Professor of Numerical Analysis and Fellow of Balliol College at the University of Oxford, a position he has held since 1997. He also has concurrent appointments as Global Distinguished Professor of Mathematics and Computer Science at New York University (2013–2019) and has served as Von Neumann Professor at TU Munich and Matheon Professor at TU Berlin in 2010.
Education:
- PhD (Computer Science/Numerical Analysis), Stanford University, 1982
- MS (Computer Science/Numerical Analysis), Stanford University, 1980
- AB summa cum laude (Applied Mathematics), Harvard College, 1977
Research Interests: Trefethen’s work centers on numerical mathematics, with particular emphasis on spectral methods, numerical linear algebra, approximation theory, numerical conformal mapping, quadrature, and pseudospectra. His research often bridges rigorous mathematical theory and practical algorithms, most notably through the widely used Chebfun software system.
Recent publications illustrate a trend toward developing fast, high-accuracy algorithms for solving classical problems such as the Laplace and Helmholtz equations, rational approximation via the AAA algorithm, and stability analysis in fluid mechanics without traditional eigenvalue techniques.
Scientific Awards:
- Pólya Prize for Mathematical Exposition (SIAM, 2017)
- Naylor Prize (London Mathematical Society, 2013)
- Gold Medal (Institute of Mathematics and its Applications, 2011)
- Fellow of the Royal Society (2005)
- Member of the US National Academy of Engineering (2007)
- ERC Advanced Grant (2012–2017)
- Honorary doctorates from Stellenbosch University and University of Fribourg (2019)
Advising & Grants: Trefethen has supervised 24 PhD/DPhil students at MIT, Cornell, and Oxford; twelve have launched academic careers. He has held major grants including an ERC Advanced Grant on “Computing with functions instead of numbers” (€2.4 M, 2012–2017) and EPSRC funding for the Chebfun System (2006–2010).
Labs & Teams: He leads the Chebfun Team at Oxford, an interdisciplinary group developing open-source software for numerical computing with functions. The team collaborates globally with researchers in mathematics, computer science, and engineering.
