Christoph Pfisterer received a Ph.D. in Philosophy from University of Zurich, Switzerland. In his doctoral thesis on the philosophy of Gottlob Frege he investigates the notion of judgment within Frege’s logic. His primary philosophical interests lie in philosophy of language, philosophy of mind, logic, and epistemology. Christoph’s current research project, which brought him to Berkeley, focuses on perception. In particular, he explores the ‘logic’ of perceptual reports in order to draw conclusions about the contents of perception.
