Rolf Haenni is a contemporary Swiss computer scientist and logician working at the Bern University of Applied Sciences, specializing in probabilistic reasoning, formal argumentation, and reasoning under uncertainty. He is known for foundational contributions to the theory of probabilistic argumentation and the epistemological justification of entropy-based inference methods.
Developed frameworks for probabilistic argumentation combining logic and probability theory
Argued for the epistemic primacy of the principle of maximum entropy over the classical Principle of Indifference
Contributed to unified theories of uncertain reasoning spanning Bayesian and non-Bayesian approaches
Applied formal argumentation methods to artificial intelligence and decision support systems
