I am the founding director and CEO of the CISPA Helmholtz Center for Information Security.

This is my research homepage. My homepage as CISPA's director can be found here.

My research interests over the years have comprised various aspects of information security and privacy, especially foundational aspects; design, analysis and verification for security-critical systems and services; methods and tools for assessing and enhancing end-user privacy; research on new attack vectors; and universal solutions in software and network security.
My current research mostly targets trustworthy machine learning in its many facets, and trustworthy information processing in general, see also my recent publications.

I'm lucky to have the chance to work with a group of outstanding graduate students and postdocs.

I am hiring new postdocs and PhD students again in different domains of information security and privacy research, specifically in, but not restricted to, the area of trustworthy machine learning and trustworthy information processing.
