Bradley K. Alpert is a computational scientist at NIST. He is probably best known for co-developing fast spherical filters. [Ruediger Jakob-Chien and Bradley K. Alpert, "A Fast Spherical Filter with Uniform Resolution," "Journal of Computational Physics", Vol. 136, pp. 580-584, 1997.] His fast spherical filters were critical in the construction of the most efficient three-dimensional fast multipole methods (FMMs) for solving the Helmholtz equation and Maxwell's equations. Other well-known work of his includes contributions to computational methods for time-domain wave propagation, [Bradley K. Alpert, Leslie Greengard, Thomas Hagstrom, "Nonreflecting Boundary Conditions for the Time-Dependent Wave Equation," "Journal of Computational Physics", Vol. 180, pp. 270-296, 2002.] [Bradley K. Alpert, Leslie Greengard, and Thomas Hagstrom, "Rapid Evaluation of Nonreflecting Boundary Kernels for Time-Domain Wave Propagation," "SIAM Journal on Numerical Analysis", Vol. 37, pp. 1138-1164, 2000.] [Bradley K. Alpert, Leslie Greengard, Thomas Hagstrom, "An Integral Evolution Formula for the Wave Equation," "Journal of Computational Physics", Vol. 162, pp. 536-543, 2000.] quadratures for singular integrals, [Bradley K. Alpert, "High-Order Quadratures for Integral Operators with Singular Kernels," "Journal of Computational and Applied Mathematics", Vol. 60, pp. 367-378, 1995.] [Bradley K. Alpert, "Hybrid Gauss-Trapezoidal Quadrature Rules," "SIAM Journal on Scientific Computing", Vol. 20, pp. 1551-1584, 1999.] and multiwavelets. [ [http://math.nist.gov/~BAlpert/alpert_pub.html Selected publications] ] Alpert was awarded the 2006 Flemming Award for his work on spherical filters and his other contributions to scientific computing.
