I am head of the information security institute at Leibniz University Hannover.
Broadly, I study the intersection of computer security and privacy with human factors. I'm particularly interested in investigating end users, administrators, developers and designers of computer systems and their interdependencies with computer security and privacy mechanisms. My research involves large-scale analyses of the Internet and software repositories to understand the huge challenges humans face when interacting with computer security and privacy mechanisms. To understand root causes, evaluate existing mechanisms and investigate novel ideas, I conduct all kinds of user studies with end users, administrators, and developers of these systems.
I completed my PhD (with distinction) supervised by Professor Matthew Smith. My PhD thesis motivates the need for ecologically valid usable-security research for end users and professional IT workers.
I am recipient of a Google Faculty Research Award and the John Karat Usable Privacy and Security Student Research Award.
My research is regularly published at top-tier venues (e.g. Oakland, CCS, USENIX Security).
