Dynamic Tractable Reasoning

​Holger Andreas studied philosophy and physics at the Universities of Leipzig and St Andrews. He completed his PhD on Carnap's logic of science in 2005, wherein he developed a novel semantics of theoretical terms. During a postdoctoral year at Stanford University in 2007, he started his work on frames and frame concepts, driven by an emerging interest in the interrelations between logic, knowledge representation, and human cognition.Following his postdoc, Andreas was Assistant Professor at the University of Bonn and at LMU Munich. Meanwhile, he was a member of the Munich Center for Mathematical Philosophy, where he completed his habilitation (postdoctoral thesis)  in 2012. After his habilitation, he was a Heisenberg Fellow at LMU Munich (funded by the German Research Foundation). He moved to Canada in 2014, where he is currently an Assistant Professor at the University of British Columbia.Holger Andreas' research interrelates philosophical logic with philosophy of science, epistemology, and cognitive science. In addition to the logical foundations of tractable reasoning, he explores conditionals and their use in logical approaches to causation and explanation.
