Research Area

My research focus is on developing and optimizing numerical methods for efficient high-performance computing. In particular, I am interested in sparse linear algebra, iterative and asynchronous methods, Krylov solvers, preconditioning. The approach I take is based on the idea of re-formulating the problems in terms of fixed-point problems to allow for higher parallelization levels. The implementation of the fixed-point methods typically make heavy use of (data-parallel) batched routines, and possess relaxed synchronization requirements. I also work on fault tolerance, energy efficiency, as well as Multi- and Manycore (GPU) computing. The algorithm research is complemented with efforts aiming at sustainable software development in an academic setting

, and a healthy software lifecycle.
