I am a PhD student at the Privacy Enhancing Technologies research unit at TU Wien in Austria, under the supervision of Dominique Schröder.

Research

I am captivated by problems that are difficult to solve and appear unsolvable at first glance. Achieving fairness in two-party protocols or preserving an individual's privacy while still enabling statistical and metric computations over an entire dataset are examples of such challenges. Though many of these problems may seem paradoxical, I am driven to resolve them using the power and elegance of cryptography. Working on such problems, my work bridges both theoretical and practical aspects. My research interests include advanced digital signatures such as adaptor signatures, secure and fair multiparty computation (including distributed key generation and threshold signatures), differential privacy, and password-based cryptography.

Education

I am pursuing my PhD under the supervision of Dominique Schröder since 2022. Initially, I began my doctoral studies at Friedrich-Alexander-University Erlangen-Nürnberg, Germany, and subsequently followed Dominique to TU Wien in 2024. Prior to my PhD, I earned a Master of Science (M.Sc.) in Computer Science from Friedrich-Alexander-University Erlangen-Nürnberg between 2020 and 2022. Earlier, I completed my Bachelor of Science (B.Sc.) in Mathematics at the University of Bonn, Germany, from 2017 to 2020.
