Biography

I am a Principal Member of the Technical Staff in the Scalable Algorithms Department at Sandia National Labs. My interests include scalable solution methods for linear systems, such as multigrid methods, preconditioning techniques for problems arising from uncertainty quantification, and solvers for advanced architectures. I am a developer of of the MueLu, ML, and Ifpack2 libraries in Sandia’s Trilinos project.
