This is my website, which serves to host some of my (professional) writings, some thoughts that I have at times and an online version of my cv.

post-quantum cryptography

My research focuses on post-quantum cryptography, specifically isogeny-based cryptography. In 2026, I received a (personal) VENI grant to pursue research on (applications of) pairings, Kummer surfaces, and the module action framework.

the isogeny club

For the first two years, I organized The Isogeny Club, together with Jonathan Komada Eriksen (www). Since, May 2024, I have stepped back and taken a more advisory role, with Maria Corte-Real Santos (www) taking over as co-host of the bi-weekly virtual seminar for young isogenists. The Isogeny Club also hosts the Brainstorm Days as an affiliated event (for all isogenists) at Eurocrypt, where we brainstorm on cutting-edge ideas in isogeny-based cryptography.

the isogeny problems

In July 20205, I reached out to a small group of leading experts and asked them what the most fundamental unsolved problems in isogeny-based cryptography were. This resulted in a curated list of 7 key problems. The resolution of any of these questions would mark a monumental advance in our field. For solving a problem on the list, you receive an epic reward, and you can also contribute your own rewards if you want. The list is available at
