Since October 2020, I am a researcher in the Cryptology Group at CWI Amsterdam headed by Ronald Cramer. A special focus of my work lies in exploring new directions in secure computation with the goal of developing practical post-quantum secure protocols.

Before coming to CWI, I worked as a postdoctoral researcher with Yuval Ishai at Technion. In 2019, I completed my PhD at Karlsruhe Institute of Technology under the supervision of Dennis Hofheinz. During my PhD, I spent eight months in the FACT center at IDC Herzliya for a research visit with Elette Boyle. I got to know the CWI Cryptology Group already back in 2015, when I wrote my master’s thesis there as a visiting student.
