Behzad Abdolmaleki is a Lecturer at the Department of Computer Science (Cybersecurity) at the University of Sheffield. He is broadly interested in constructing cryptographic schemes in post-quantum and quantum settings and the intersections with other disciplines, e.g., zero-knowledge proofs, MPC, cryptocurrencies, and concurrent systems.
From Nov. 2020 to April 2023, he was a postdoctoral researcher in Cryptography at the Max Planck Institute for Security and Privacy (MPI-SP), Germany, where he was working with Giulio Malavolta. Prior to joining MPI-SP, he was a senior researcher in Cryptography at the University of Tartu (from August to December 2020). He finished his Ph.D. at the University of Tartu on September 2020, under the supervision of Helger Lipmaa. In August and November 2019, he visited the AIT Austrian Institute of Technology, Vienna, Austria, hosted by Daniel Slamanig.
