About

I'm a Ph.D. candidate at the Ruhr University Bochum and member of the Horst Görtz Institute for IT Security. Currently, I'm working as a research assistant at the Usable Security and Privacy Section of the Leibniz University Hannover. I'm also part of the Usable Security and Privacy Lab at the George Washington University. My advisor is Prof. Dr. Markus Dürmuth. My research interests lie in the intersection of information security, human-computer interaction (HCI), and privacy with an emphasis on authentication methods and privacy enhancing technology.
