This is the homepage of Uli Fahrenberg, mathematician / computer scientist. It is deliberately kept short to be (hopefully) more easily maintainable.

I am professor at EPITA Rennes and at LRE, and head of the Automata and applications research group at LRE. I am also associated with IRISA Rennes, where I am a member of the SUMO group, and with the Cosynus group of LIX, École polytechnique. I have a PhD in mathematics from Aalborg University and have worked at Aalborg University, IRISA Rennes, and École polytechnique.


I have defended my habilitation à diriger des recherches at the University Paris-Saclay on 10 May 2022. My thesis is entitled A Generic Approach to Quantitative Verification and available on arxiv. The jury for the defence was composed of Christel Baier, Dresden; Paul-André Melliès, Paris; Rob van Glabbeek, Sydney; Nathalie Bertrand, Rennes; Patricia Bouyer-Decitre, Saclay; and Georg Struth, Sheffield/Lyon.

Une traduction française du premier chapitre de mon habilititation est disponible sur hal, sous le titre Une approche générique à la vérification quantitative. Merci à Aline Fahrenberg pour la traduction.


My research is in the areas of real-time systems, quantitative verification, directed algebraic topology, concurrency theory, and in categorical foundations for theoretical computer science. I keep an up-to-date list of publications.
