Our research is based on laboratory experiments to obtain insights into dynamical phenomena: from the dynamics of fluid flows to the crystallisation of polymers. Experimental research often leads to surprises, new structures and new materials. For example the swelling of gels or the stretching of viscoelastic polymer filaments led to unexpected phenomena. The understanding, interpretation and reuse of these phenomena are possible through a combination of more experiments, theory and numerical modeling. In additon, I enjoy playing with old problems including the transition to turbulence in Couette-Taylor and Poiseuille flows or the crystallisation of hydrates.
