I received my Ph.D.in Applied Mathematics from Cornell University in 1996, under the supervision of L. N. (Nick) Trefethen. I was an NSF Postdoctoral Fellow in Applied Math at the University of Colorado in Boulder with Bengt Fornberg, then joined the faculty in the Department of Mathematical Sciences at the University of Delaware in 2000. I became a full professor in 2010 and Director of Graduate Studies in 2011. In 1999 I received a SIAM Outstanding Paper Prize, and in 2002 I was a Winner of the SIAM 100-Digit Challenge.
My research has focused on spectral and high-order numerical methods for differential equations, including Chebyshev collocation, radial basis functions, and specialized methods for time stepping. I am the author of the Schwarz-Christoffel Toolbox for MATLAB, which computes conformal maps to polygonal regions, and I am a key contributor to the Chebfun project at Oxford University for numerical computing with functions. I have written two books. I have also coauthored papers on applications of math and computing with collaborators in electrical engineering, physics, materials science, biology, and medicine.
