Argonne Scholar


Johann Rudi received his Ph.D. from ICES, the University of Texas at Austin.  He won the ACM-IEEE CS George Michael Memorial HPC Fellowship in 2016 for his project Extreme-Scale Implicit Solver for Nonlinear, Multiscale, and Heterogeneous Stokes Flow in the Earth’s Mantle” and the ACM Gordon Bell Prize in 2015 for his work on an extreme-scale implicit solver for complex PDEs.

Research Interests

  • Nonlinear Stokes flow
  • Scalable iterative solvers for nonlinear and linear systems
  • Multigrid and multilevel methods
  • Simulation of Earth’s mantle
