Research Homepage

I am tenure-track faculty at the Center of IT-Security, Privacy and Accountability (CISPA) in Saarbrücken. The focus of my research is public key encryption and secure two-party computation.

From 2017 to 2018 I was assistant professor at the Friedrich-Alexander-University Erlangen Nürnberg. Prior to that, I was a postdoc in the group of Sanjam Garg at UC Berkeley, supported by a DAAD fellowship from 2016 to 2017 and a postdoc in the crypto group of Aarhus University, working with Ivan Damgård and Jesper Buus Nielsen form 2014 to 2016. I finished my PhD in 2014 at the Karlsruhe Institute of Technology under the supervision of Jörn Müller-Quade. I am the 2014 winner of the biennial Erika and Dr. Wolfgang Eichelberger Dissertation Award.

Thesis
My PhD thesis, available here, is about the construction of advanced cryptographic primitives from coding problems.
