Stephan Dübler

Since January 2023 I have been a PhD Student at the Heinz Nixdorf Research Group for Cryptocurrencies and Smart Contracts at the Max Planck Institute for Security and Privacy (MPI-SP). I am interested in formal methods and the theoretical foundations of distributed systems as well as microarchitectural security. With a background in mathematics, I am especially concerned with provable security guarantees.

Prior to my work at MPI-SP, I completed my Bachelor’s (2020) and Master’s Degree (2022) in Mathematics at Ruhr University Bochum. Besides my university education, I gained profound practical experience in algorithm design and data science during my work at the Fraunhofer Institute for Software and Systems Engineering.
