My doctoral research revolves around post-quantum cryptography and cryptanalysis with a special focus on isogeny-based cryptography. More generally, I am interested in computational number theory and various applications of pure mathematics to cryptography.
Before joining Royal Holloway, I obtained a BSc in Mathematics from the Free University of Berlin, an MSc in Pure Mathematics from Imperial College London and an MSc in Mathematics and Foundations of Computer Science from the University of Oxford.
