My research interests focus in computational materials science, especially in microstructure evolution due to phase transitions on the mesoscale, and in scale-bridging modeling of material and device behaviour. A central point of my work is thermodynamic modeling and development of numerical methods for coupled deformation- and transport processes (diffusion, advection) and thermoelasticity.
I have a special interest in new software concepts, for the topic of efficient, parallelized algorithms in high performance computing, and in quantitative analysis and visualization of large data sets. I have guided the implementation of coupled elastic, micromagnetic and flow processes on simulation platforms, as well as advanced methods for parameter generation.
The material systems I study include multicomponent alloys (solidification, grain growth), minerals/oxides and functional materials (shape memory alloys), for which I develop scale-bridging methods to integrate the complex material behaviour into the device design. Applications studied are energy-efficient microcooling, vibration control and energy harvesting. In this scope, I study real time methods for the system dynamics of thermomechanical material behavior.
Furthermore, I have particular interest in geomaterials and related questions from geosciences. This includes partial melting of rock, the influence of crystallization and wetting on fluid permeability in fractured, porous rocks with applications in geothermal energy and reservoir geology.
