My research is on experimental soft condensed matter physics and non-equilibrium physics. In particular I have investigated the flow properties and flow instabilities of granular media and foams. I have employed and developed novel techniques in magnetic resonance imaging as well as high speed imaging to elucidate the role of interstitial gas in granular size separation and to study shear flow in granular media. Moreover, I have discovered a novel flow instability in granular jets. This research has lead to publications in high impact journals. Present research interests: Connection between bulk rheology and bubble dynamics in foams. For this research, we combine rheometry and image processing based on custom software to investigate shear-induced bubble dynamics. In collaboration with Dr. Stefan Hutzler we employ simulations to complement the experimental results.
