Research Areas
 Analysis of modern, high-order, unstructured, finite-element methods. Development of associated efficient algorithms, including parallel computational techniques, adaptivity, and advanced preconditioning methods for solving linear systems. Scientific computing applications for these methods including electromagnetics, acoustics and computational fluid dynamics in complex geometries. Simplification and introduction of these techniques to academic, defense and industrial environments. Development of artificial radiation boundary conditions for the time-domain Maxwell's equations. Architecturally tuned numerical algorithms, in particular GPGPU accelerated computing using CUDA and OPENCL.
