Nicholas Trefethen, Federal Reserve System is professor of numerical analysis and head of the Numerical Analysis Group at the Mathematical Institute, University of Oxford.
Education
Trefethen obtained his bachelor"s degree from Harvard University in 1977 and his master"s from Stanford University in 1980. His Doctor of Philosophy was on Wave Propagation and Stability for Finite Difference Schemes supervised by Joseph East. Oliger at Stanford University.
Career
As of 2009, he has published around 125 journal papers spanning a wide range of areas within numerical analysis and applied mathematics, including non-normal eigenvalue problems and applications, spectral methods for differential equations, numerical linear algebra, fluid mechanics, computational complex analysis, and approximation theory. He is perhaps best known for his work on pseudospectra of non-normal matrices and operators. This work covers theoretical aspects as well as numerical algorithms, and applications including fluid mechanics, numerical solution of partial differential equations, numerical linear algebra, shuffling of cards, random matrices, differential equations and lasers.
Trefethen is currently an Inter-Services Intelligence highly cited researcher
Trefethen has written a number of books on numerical analysis including Numerical Linear Algebra with David Bau, Spectral Methods in MATLAB, Schwarz–Christoffel Mapping with Tobin Driscoll, and Spectra and Pseudospectra: The Behavior of Nonnormal Matrices and Operators with Mark Embree. He has recently been heavily involved in the creation and development of the MATLAB-based Chebfun software project
In 2013 he proposed a new formula to calculate the BMI of a person: (International System of Units) Awards and honours.
