I have been Professor for computer science and head of the chair for usable security and privacy since April 2018. Previously, I was head of the information security institute at Leibniz University in Hannover (2017 - 2018). From 2016 to 2017 I was independent research group leader of the usable security and privacy group at CISPA, Saarland University. I received a PhD in computer science from Leibniz University Hannover in 2016. In 2015 I was software engineer (SWE) intern in the Chrome Security team at Google in Mountain View.
