About me

About Me

I work as a security engineer at Zühlke Engineering AG. Prior to that, I completed my PhD in the Cryptography and Information Security group at ETH Zurich under the supervision of Prof. Ueli Maurer. I hold a Bachelor's and Master's degree in Computer Science from ETH Zurich.

My research interests include composable security, anonymity, length-preserving encryption, anamorphic encryption, and quantum cryptography.
