I am currently a research assistant at the chair of computer engineering at the University of Passau under the direction of Prof. Dr. Stefan Katzenbeisser. Before that, I was a research assistant and a PhD student at the Technical University of Darmstadt under the direction of Prof. Dr. Stefan Katzenbeisser. I have worked in the DFG Projects CROSSING P3, NanoSec, and PUFMem. I am also currently the Chair of the German Chapter of the IEEE Consumer Technology Society, the Vice Chair of the German Chapter of the IEEE Circuits and Systems Society, and the Secretary of the German Chapter of the IEEE Solid-State Circuits Society. Finally, I am also the current Vice Chair of the Greek university group at the University of Passau.
