I research and teach analytic philosophy at Instituto de Investigaciones Filosóficas (UNAM). At the moment I’m working on a book about the great Alonzo Church, with Harry Deutsch, for Oxford University Press. Other than that, my goal is to describe a philosophy of language suitable for mathematical language, in order to better understand how we acquire mathematical knowledge.
