Personal profile

Research profile

I am an assistant professor in the Coding Theory and Cryptology group at TU Eindhoven. My research focuses on post-quantum cryptography – cryptography that resists quantum computer-aided attacks. My works range from theoretical works, like how to model quantum attacks or formal security arguments in post-quantum security models, to applied works, like the analysis of side-channel attacks or the development of efficient hash-based signature schemes.  In many of my works I try to combine the theoretical and the applied perspective. This is especially reflected in my work on standardizing post-quantum cryptography. To learn more about my research, have a look at my personal homepage.

Before my current position, I was a postdoctoral researcher in the Coding Theory and Cryptology group, working with Tanja Lange in the PQCRYPTO project. Before I was a postdoctoral researcher in the cryptographic implementations group at TU Eindhoven, working with Daniel J. Bernstein. I did my PhD in the cryptography and computer algebra group at TU Darmstadt under the supervision of Johannes Buchmann. Before starting my PhD, I worked as a research fellow at Fraunhofer SIT in Darmstadt. I hold a Diploma in computer science from TU Darmstadt.
