Stefan Kiefer is a Professor of Computer Science at the University of Oxford and Tutorial Fellow in Computer Science at St John's College. He holds a Dr. rer. nat. from TU München (2009) and has held postdoctoral positions at Oxford since 2009. His research focuses on formal verification, probabilistic models, and automata theory, with applications in program analysis and infinite-state systems. Kiefer has been recognized with a Royal Society University Research Fellowship (2013–2021) and is a member of the EPSRC Peer Review College. Research Interests: Verification, probabilistic systems, infinite-state systems, automata theory, numerical analysis, and linear algebra. His work addresses challenges in analyzing probabilistic systems to ensure correctness in safety-critical systems. Teaching: Leads tutorials in Probability and Computing, Linear Algebra, and supervises DPhil students. Current advisee: Syyeda Zainab Fatmi. Past students include Ines Marusic, Cas Widdershoven, and Oscar Darwin. Grants & Awards: EPSRC grants, Royal Society funding, and active roles in professional service, including co-chairing FoSSaCS'21 and speaking at conferences like ICALP and Highlights. Publications: Over 50 papers on topics like Markov decision processes, automata minimization, and probabilistic verification, published in venues such as ICALP, CONCUR, and the Journal of the ACM.
