Predoctoral Researcher

Bio

I am a predoctoral researcher at IBM Research in Zürich. My main interest lies in the design of cryptographic protocols, multi-party computation and universal composability.

Currently, I'm pursuing a PhD at ETH Zürich under the supervision of Prof. Dr. Dennis Hofheinz and Dr. Julia Hesse.

I studied computer science at KIT in Karlsruhe, Germany.
