My research focuses on the security and privacy aspects of information technology. I am motivated to understand new technologies rapidly, to quantify and systematize system properties. Uncovering tension points and tradeoffs in terms of security, privacy and performance is an exciting endeavour - especially when those apply faithfully to real world systems.
My research is inherently multidisciplinary and I frequently collaborate with colleagues worldwide in various fields, in particular data science and machine learning.
