Numerical analysis, scientific computing, and numerical algebraic geometry
I am interested in the study and development of numerical algorithms in applied mathematics. I mainly work in the following three areas: (1) Novel spectral methods for the solution of differential equations, (2) The asymptotics of special functions for image reconstruction, convolution, and quadrature, and (3) Numerical algebraic geometry for the solution of polynomial systems.
