About

I focus on applied cryptography and the design of new cryptographic protocols. My research bridges the gap between theory of cryptography and practice. I produce solutions which do not only have a solid theoretical foundation, but are practical and efficient in the real-world. Cryptographic techniques that I have designed are deployed in aircraft such as the Airbus A320, the highest-selling commercial aircraft family.

In reverse chronological order, my major contributions so far have been in the design of

As a principal investigator, my own research projects have been funded by NSF and VISA Inc. My work is published in top venues (such as CCS or NDSS) and has been distinguished with several best paper awards.

Before joining Airbus’ Cyber Research Center, I was research assistant professor at Northeastern University, Boston USA, and senior researcher at EURECOM, France. I hold Diploma and PhD (with distinction) in computer science from University of Karlsruhe in Germany. My thesis was awarded with the prize for the best security research thesis by Germany’s data security organization GDD in 2007.
