Short CV

I am a postdoc at Saarland University in the group of Prof. Jan Reineke, since January 2025. My research interests include reverse engineering of microarchitectures, and security. I completed my PhD at ENS Paris and IRISA/Inria in January 2023 with a thesis entitled Studying hardware prefetchers using cache side channels.
