I am an ORISE faculty at the U.S. Army Research Laboratory, Aberdeen Proving Ground, Maryland. I am also a faculty member (adjunct) at Wayne State University in the Department of Mathematics. I have been a faculty member at TOBB ETU in the Department of Mathematics and Louisiana State University in the Department of Mathematics and in the Center for Computation & Technology. I was also an adjunct faculty at the University of New Mexico, in the Department of Mathematics and Statistics. My research has been funded by National Science Foundation, European Commission Marie Curie Program, and Scientific and Technological Research Council of Turkey.
Research Interest/Area of Expertise
I work in the areas of numerical analysis, scientific computing, and numerical linear algebra. My research interests include:
Preconditioning, iterative solvers, numerical solutions to partial differential equations, multilevel preconditioning, multigrid, preconditioning under adaptive mesh refinement, robust preconditioning for high-contrast heterogeneous media, nonlocal problems, peridynamics, local boundary conditions for nonlocal problems, preconditioning for peridynamics, scalable solvers for nonlocal problems, Krylov subspace solvers.
