I am a postdoctoral researcher in the Pietrzak Group at IST Austria.
The scope of my research is provable security in public-key cryptography and its foundations. I have worked on public-key encryption, digital signatures, credentials, electronic cash, and combining game theory with cryptography.
In 2010 I finished my PhD at
École normale supérieure, Paris, and then worked in the
Cryptography Group at the University of Bristol, where I was also lecturing.
