After a well-traveled childhood, Martino completed a Ph.D in philosophy at Cornell University. He then taught philosophy for a few years in the States before returning to Italy. Here, he teaches college courses in ethics, Italian culture, and history at various study-abroad programs. He has lectured at the British Institute in Florence on contemporary moral topics. Teaching rekindled his interest in Dante and "The Divine Comedy," as well as the controversy between Galileo's astronomy and the Church. Martino lives in the countryside with his wife and their too many dogs.
