Über mich

Von 2006 bis 2011 habe ich an der RWTH Aachen Computational Engineering Science studiert. Meine Promotion zum Thema "Stabilisierte Finite Elemente Methoden für blutführende Medizinprodukte" konnte ich im Sommer 2016 abschließen. Seitdem bin ich als Postdoc tätig und war über ein Theodore-von-Kármán-Fellowship auf Forschungsaufenthalt an der Stanford University. Zudem leite ich die Strukureinheit "Modellierung" im Profilbereich Computational Science and Engineering CompSE und bin aktives Mitglied der GAMM-Juniors.
