Tzanio Kolev is a computational mathematician at the Center for Applied Scientific Computing of Lawrence Livermore National Laboratory (LLNL) where he works on efficient finite element discretizations and solvers for problems in compressible shock hydrodynamics, multi-material ALE, computational electromagnetics, and other application areas. He joined LLNL in 2004 after earning a PhD in Mathematics from Texas A&M University. Tzanio is the director of the Center for Efficient Exascale Discretizations (CEED) in the Exascale Computing Project and the project leader of several projects at LLNL, including MFEM, BLAST and ETHOS. Tzanio’s research interests include the development and analysis of finite element discretizations, high-order methods and applications, performance optimizations and scalability, discretization-enhanced multigrid solvers, and the design and implementation of large-scale scientific software. His work on AMS – the first provably scalable solver for electromagnetic diffusion problems, was selected as one of the top ten breakthroughs in computational science in a 2009.
