Stephan Dübler

Since January 2023 I have been a PhD Student at the Heinz Nixdorf Research Group for Cryptocurrencies and Smart Contracts at MPI-SP. I am interested in the theoretical foundations of blockchain-based distributed applications. With a strong background in mathematics, I am especially concerned with provable security guarantees.

Prior to 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 by working at the Fraunhofer Institute for Software and Systems Engineering as a working student.
