Ketan Mittal is a postdoctoral researcher at the Center for Applied Scientific Computing (CASC) where he is involved in the ETHOS and MFEM projects. Ketan's research interests are driven by methods that can improve computational efficiency of numerical simulations and reduce time-to-solution. Some of the research areas that he is currently engaged in are automated high-order mesh generation and optimization methods, overlapping Schwarz-based solvers, multirate time-stepping techniques, and improving predictor-corrector methods using linear stability analysis. The methods that Ketan has developed are available through MFEM (a high-order finite element library), Nek5000 (spectral element method based solver for the incompressible Navier-Stokes equations), and gslib (a highly scalable communication library for nearest neighbor exchanges in FEM and SEM).
Prior to coming to CASC, Ketan got his Ph.D. from the University of Illinois at Urbana-Champaign (UIUC) under the advisement of Prof. Paul Fischer. At UIUC, Ketan developed a high-order mesh smoother and an overlapping grid based solver for the incompressible Navier-Stokes equations (NekNek).
