Overview
Since February 2023 I have been working for NXP Semiconductors in Leuven as part of the cryptography team led by Joppe Bos. Before that I was a postdoc at the University of Wuppertal, working in Tibor Jager's IT Security and Cryptography group, as part of the REWOCRYPT project.
I have recently or am currently serving on committees for CT-RSA 2023, SSR 2023 and CCS 2023.
