Veselin Dobrev is a postdoctoral researcher in the Computational Mathematics group in the Center for Applied Scientific Computing. His research interests are in the areas of: numerical methods for PDEs including finite element and discontinuous Galerkin methods; shock hydrodynamics simulations; iterative and multigrid methods; L_{1} minimization.
Veselin received his Ph.D. in Mathematics from Texas A&M University in 2007. He is currently working on high-order curvilinear finite elements for Lagrangian hydrodynamics (BLAST project).
