About Me

As a Materials Scientist turned Mechanics researcher my research interests are in understanding the underlying physics of material behavior through computational mechanics. This requires inevitably developing algorithms for material behavior in different length scales as well as computational and analytical methods for scale transition. With the help of these then physically based material models at the macroscopic scale are developed which need fewer parameters and possess predictive capabilities.
