LLOYD N. TREFETHEN - BRIEF BIOGRAPHY (November 2007) Nick Trefethen is Professor of Numerical Analysis and head of the Numerical Analysis Group at Oxford University. He was educated at Harvard and Stanford and held professorial positions at NYU, MIT, and Cornell before coming to Oxford in 1997. He is a Fellow of the Royal Society and a member of the US National Academy of Engineering. As an author he is known for his books Numerical Linear Algebra (1997), Spectral Methods in MATLAB (2000), Schwarz- Christoffel Mapping (2002), and Spectra and Pseudospectra (2005). He is an ISI Highly Cited Researcher, with about 90 journal publications in numerical analysis and applied mathematics, and has served as editor for many of the leading numerical analysis journals. He has lectured in about 15 countries and 25 American states, including invited lectures at both ICM and ICIAM congresses. Some of Trefethen's recent activities include the SIAM 100-Dollar, 100-Digit Challenge, the notion of Ten Digit Algorithms ("ten digits, five seconds, and just one page"), the chebfun system for numerical computation with functions instead of numbers, and a book in preparation called Neoclassical Numerics.
