Research Interests

The main research interests are molecular dynamics and continuum mechanical simulations of solids. Of special interest are the relationship between both length scales and upscaling techniques for the derivation of continuum mechanical models from atomistic models. As an application, I am interested in microstructure and martensitic phase transformations in shape memory alloys (click here for an introduction).
