Subject

Currently, my work is focussed on magnetic gels and elastomers. They are soft elastic materials, into which magnetic particles are embedded. Through the interplay of the elasticity of the matrix and the magnetic properties of the particles, the sample's shape and elasticity can be controlled by means of external magnetic fields. Predicting this behaviour accurately is, however, rather difficult, as, typically several effects are at work at the same time. We approach the topic using computer simulations, as they allow for precise control of individual aspects of the models, and we can study the relevant mechanisms separate from each other.

I am also involved in work on nanoparticles in a flow and micro-rheology, in particular, the irreversible agglomeration of soot particles in turbulent flow as well as the study of local jamming effects in optical tweezer experiments.

I am interested in the development of simulation software and am a contributor to the ESPResSo molecular dynamics package.
