He was additionally appointed Professor of Linguistics in 2009.

André Fuhrmann has made contributions in analytic philosophy, relevance logic and modal logic. Fuhrmann is best known for his research on "belief revision" or "theory change", a field of formal epistemology with applications for artificial intelligence and cognitive science. Fuhrmann also takes an interest in freshwater diatoms. Together with H. Lange-Bertalot he discovered and described new species, particularly in the genus Diploneis.
