I am a mathematician working in the field of numerical analysis and high performance parallel computing. I tend to specialize in the worst case analysis of algorithms and the development of algorithms that cannot fail. I am a co-author of the StarNEig library for solving dense nonsymmetric standard and generalized eigenvalue problems in parallel. I am currently working on the development of parallel constraint solvers for constrained molecular dynamics and parallel solvers for ultra-sparse linear systems.

I teach numerical analysis and scientific computing . My long term objective is to teach my students how analyse and design algorithms for solving complicated problems using modern computers. My focus is on the profound difference between the exact arithmetic used by humans and the finite precision arithmetic used by computers. I also invest a lot of time in teaching my students how to write and document software and how to structure their written reports
