Research

My current research interests are mainly in numerical linear algebra, in particular in large-scale matrix computations and sparse matrix computations, dimension reduction of dynamical systems, and large-scale optimization problems. Much of my research is motivated by computational problems arising in science and engineering; examples include VLSI circuit simulation and the mathematical modeling and simulation of fiber-optic communication systems.
