BIO
I am an Assistant Professor at the Department of Computer Science and a member of the Security of Advanced Systems research group at the University of Sheffield, UK. I am broadly interested in constructing cryptographic schemes in post-quantum and quantum settings and the intersections with other disciplines, e.g., zero-knowledge proofs, cryptocurrencies, and concurrent systems.
From Nov. 2020 to April 2023, I was a postdoctoral researcher in Cryptography at the Max Planck Institute for Security and Privacy (MPI-SP), Bochum, Germany, where I was working with Giulio Malavolta. Prior to joining MPI-SP, I was a senior researcher in Cryptography at the University of Tartu (from August to December 2020). I finished my Ph.D. at the University of Tartu in September 2020, under the supervision of Helger Lipmaa.
Research visit: In August and November 2019, I visited the AIT Austrian Institute of Technology, Vienna, Austria, hosted by Daniel Slamanig. In October 2022, I visited the Friedrich-Alexander University of Erlangen-Nuremberg, Germany, hosted by Dominique Schröder.
PhD Students: Jiaqi Gu, Nahid Roustaeifar
