Stephan Gekle is a theoretical physicist heading the Biofluid Simulation and Modeling Group at the University of Bayreuth (Germany). He studied physics in Stuttgart (Germany) and Valladolid (Spain). In 2009, he obtained his PhD from the University of Twente (The Netherlands) on the splashing of water surfaces after the impact of an object. During his PostDoc between 2009 and 2012 at the Technical University of Munich (Germany) he became interested in biological physics questions. Since 2012, he is leading his own research group at the University of Bayreuth (Germany) with a particular focus on modeling of blood flow.
