Christophe Erismann has held research fellowships at the University of Cambridge, the Warburg Institute in London, Harvard University's Dumbarton Oaks Research Library, and Helsinki University. He taught medieval philosophy for several years at the University of Lausanne as Swiss National Science Foundation Professor. His research focuses on the reception of Greek logic (mainly Aristotle's Categories and Porphyry's Isagoge) in late Ancient, Patristic, and Early Medieval Philosophy. The recent focus of his work is on the logical tradition in the writings of ninth-century Byzantine authors, such as Theodore the Stoudite, the patriarch Nikephoros and Photius.
