Gemes earned his PhD from the University of Pittsburgh in 1990 with a dissertation in philosophy of science working with Clark Glymour and Wesley Salmon. He taught at Yale University for ten years before moving to Birkbeck in 2000.^[1]

Gemes's work has covered a wide range of philosophical issues, from technical concerns of logical content to Nietzsche's account of philosophy as the "last manifestation of the ascetic ideal".^[2]
