Research/Teaching

My primary interests are matrix theory and numerical analysis. Much of my research involves fast algorithms for structured systems of equations and the analysis of their numerical stability. I am more generally interested in matrix problems with applications in signal processing and control theory.

I primarily teach courses in applied math and matrix theory.
