Matthias Krack

Dr. Matthias Krack is a Researcher and Deputy Head of the Laboratory for Materials Simulations at Paul Scherrer Institute's Center for Scientific Computing. He leads the Multiscale Materials Modelling Group specializing in computational nuclear materials.

His research combines ab initio simulations with experimental techniques to study radiation damage, radionuclide interactions, and nuclear fuel performance. Current investigations focus on magnetite surfaces for radioactive waste containment and validation of density functional theory methodologies.

Publications examine incorporation mechanisms of technetium in iron oxides, surface solvent interactions, and defect behavior in uranium dioxide. He co-develops the CP2K software package and contributes to international projects on nuclear fuel licensing and safety.

Research projects include:

• Horizon 2020 INSPYRE (nuclear fuel modeling)
• SNF project on metal adsorption in clay minerals
• CSCS initiatives on radiation damage simulation
