Iris Christadler studied Computer Science at the University of Erlangen-Nuremberg, Germany. Her studies, which she finished in 2004, were already centered on the fields of HPC computing, fluid dynamics, and multigrid methods. She wrote a term paper about patch-adaptive relaxation used as a smoother in a multigrid solver. The subject of her diploma thesis (MSc equivalent) was multigrid algorithms for the computation of optical flow problems using non-standard regularizers. She is currently working on highly optimized multigrid methods for image registration problems in close cooperation with Prof. Ruede at the University of Erlangen.
