Teaching highlights

Currently teaching

Matrix Computations (CS 6210)

Bard 140. TR 1:00-2:15.

Numerical linear algebra. Basic theory, efficient algorithms, and enough error analysis to avoid numerical embarrassment (we hope)! Direct and iterative methods for linear systems, least squares, and eigenvalues.

SCAN Seminar (CS/MATH 7290)

    Ongoing. M 1:30-2:20.

    The Scientific Computing and Numerics seminar series focuses on various methods in scientific computing, the analysis of convergence properties and computational efficiency, and their adaptation to specific applications.
