About

I am an associate professor leading the Applied and Provable Security (APS) group at Eindhoven University of Technology (TU/e) as well as a principal research scientist at SandboxAQ. My research group and I are currently supported by NWO under the Vidi grant “A solid theory for post-quantum cryptography”. Besides, I am collaborating in the Formosa project to produce machine-checked proofs for high-assurance cryptographic software.  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 publications and talks page.

Previously, I held positions as assistant professor and postdoctoral researcher in the Coding Theory and Cryptology group, working with Tanja Lange in the PQCRYPTO project. Before that I was a postdoctoral researcher in the cryptographic implementations group at TU/e, 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.
