About
I am a doctoral student at the Privacy Enhancing Technologies research unit at TU Wien in Austria, under the supervision of Dominique Schröder. My research is supported through the Google PhD Fellowship in Privacy, Safety, and Security.
I received an M.Sc. in Computer Science from FAU Erlangen-Nürnberg (2020–2022), specializing in security and cryptography. I also hold a B.Sc. in Mathematics from the University of Bonn (2017–2020), with a focus on lower-dimensional algebraic topology, in particular Riemann surfaces.
My research focuses on the design and analysis of advanced cryptographic protocols. In particular threshold signatures, partially-oblivious pseudorandom functions (PoPRFs), and password-based cryptography. I am especially interested in achieving strong security guarantees in challenging settings, and in developing constructions that are both theoretically sound and practically efficient.
