Bio

I am a PostDoc with a joint appointment at UC Berkeley (working with Sanjam Garg) and at Carnegie Mellon University (working with Vipul Goyal). I work on cryptography and security at large with a particular interest on the theory and applications of public-key cryptography.

In fall 2019 I was a research fellow at the Simons Institute for the Theory of Computing. I completed my Ph.D. in June 2019 at Friedrich-Alexander University under the supervision of Dominique Schröder. During summer 2017 I was visiting Sanjam Garg at UC Berkeley. Prior to that, I completed my M.Sc. at Saarland University in December 2016.
