I completed my doctoral degree at the University of Freiburg in 1974 with a thesis on identity and synonymy in logic and semantics and subsequently taught at the universities of Oxford and Cambridge and at Michigan State University. My research during this time focused on theories of meaning for natural languages and intensional semantics, and I continued working in this area at the University of California at Berkeley, St. John’s College (Oxford), Harvard University and at Wolfson College (Oxford). In 1985, I was awarded my habilitation at the University of Regensburg (Dr. phil. habil.) with a thesis on Frege’s philosophy of mathematics. Since 1987 I have held a distinguished Fiebiger-Professorship at the University of Munich (LMU) and since 2012 I have been a member of the Munich Center for Mathematical Philosophy. I have also taught at the University of Minnesota (1989), the State University of Campinas (1991), the Catholic University of São Paulo (1998), the National University of Buenos Aires (1992), the National Autonomous University of Mexico (1993, 1994, 1997), the National University San Marcos in Lima (2009) and numerous other universities in Europe and Latin America. I have published in Mind, The Philosophical Review, The Philosophical Quarterly, Synthese, Erkenntnis, Axiomathes, The Journal of Symbolic Logic, Reports an Mathematical Logic, History and Philosophy of Logic, Logique et Analyse, The British Journal for the Philosophy of Science, Metascience, Dialectica, Grazer Philosophische Studien, Kantstudien, Archiv für Geschichte der Philosophie, Theoria, Crítica, Manuscrito and other international journals. I have given invited lectures at the most prestigious universities in Europe, Asia, Latin America and South Africa as well as at some of the most distinguished universities in the United States of America and Australia. In 2014, I delivered a series of lectures on Frege’s philosophy of mathematics at the University of Oxford and carried out related research at Wolfson College. In the same year, I was invited to work as a research professor at Kyoto University and received a research fellowship from the Japan Society for the Promotion of Science.
