About me

I studied Computational Engineering Science at RWTH Aachen from 2006 till 2011 and finished my PhD on "Stabilized Finite Element Methods for Blood-Handling Medical Devices" during summer 2016. Since then, I am working as a postdoc and went on a research stay to Stanford University thanks to a Theodore-von-Karman-Fellowship. In addition, I am heading the unit "Modeling" of the profile area Computational Science and Engineering CompSE and I am an active member of the GAMM-Juniors.
