Tzanio Kolev is a computational mathematician at the Center for Applied Scientific Computing, where he works on efficient finite element discretizations and solvers for problems arising in various application areas, such as compressible shock hydrodynamics, multi-material ALE simulations, radiation-hydrodynamics and computational electromagnetics.

Tzanio is the director of the Center for Efficient Exascale Discretizations, a co-design center in the Exascale Computing Project. He is also the project leader of the MFEM finite element library, and the High-Order Curvilinear Finite Elements for Shock Hydrodynamics (BLAST) and the Enabling Technologies for High-Order Simulations (ETHOS) projects. He was formerly a member of the Scalable Linear Solvers (hypre) and the Parallel Time Integration with Multigrid (XBraid) projects. 

Tzanio's research interests include the development and analysis of advanced finite element discretization methods, massively parallel preconditioners, discretization-enhanced algebraic multigrid algorithms, and the design and implementation of large-scale scientific software. He joined Lawrence Livermore National Laboratory in 2004 after earning a Ph.D. in Mathematics from Texas A&M University. His dissertation was on least-squares methods for electromagnetic problems.
