I am a postdoctoral researcher at TU Eindhoven working with Tanja Lange in the PQCRYPTO project. My research focuses on post-quantum cryptography – cryptography that resists quantum computer-aided attacks. My main goal is to get post-quantum cryptography into practice. To achieve this, it is necessary to develop schemes for which reliable security estimates can be made and that meet practical performance requirements. A lot of my research is on hash-based signatures and led to an IRTF Internet draft, recently. To learn more about my research, have a look at my publications and talks page.
Before my current position, 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, mainly carrying out applied research in PKI and smartcard projects. I hold a Diploma in computer science from TU Darmstadt.
