Ketan Mittal is a Computational Mathematician in the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory. His expertise spans high-order mesh generation and optimization techniques, data-driven adaptive mesh refinement, field-evaluation at arbitrary points on curved meshes, computational geometry, scalable algorithms for particle-based discretizations, and GPU-accelerated FEM.

The methods that Ketan has developed are available through open-source libraries: MFEM, Nek5000, and gslib.  Some of his notable contributions include TMOP-based mesh optimization (MFEM); FindPointsGSLIB for evaluating functions at arbitrary points on high-order volume and surface meshes (MFEM); a general particle framework (MFEM); extending gslib’s findpts to support an arbitrary number of overlapping meshes (gslib); an overlapping-grid solver for incompressible Navier–Stokes equations (Nek5000); and mesh-smoothing techniques for spectral-element meshes (Nek5000).

Ketan served on the organization committee of the SIAM International Meshing Roundtable as the Research Notes Chair (2023) and Paper Chair (2024), leading to editorial roles for a special issue in the Computer-Aided Design journal and the book for SIAM IMR proceedings. Ketan has served as a reviewer for NSF and several internationally reputed journals and conferences including Journal of Computational Physics, Engineering with Computers, IEEE TNNLS, ICML, and NeurIPS.
