I am a postdoctoral researcher working on nanoelectronic devices and materials characterization at the Transport at Nanoscale Interfaces Laboratory. I joined the laboratory in August 2016 after moving from the Department of Physics at the University of Basel. From October 2014 to October 2019 I was a member of the PhD School at the Swiss Nanoscience Institute at the University of Basel, pursuing a PhD under the supervision of Prof. Michel Calame.

From 2007 to 2013 I studied Physics at Technical University of Munich with an interim stay at the University of Manchester. In between my Diploma-thesis in the group of Prof. Alexander Holleitner and the start of my PhD I worked as a Consultant at Strategy Engineers GmbH.

Besides my focus on better understanding the properties of graphene nanoribbons and their integration into nanoelectronic devices with Raman spectroscopy, I am also looking for new ways to apply this technology to other nanomaterials, molecular thin films, and biomedical samples.

Research interests
