My primary interest is in the philosophy of physics, including mathematical and conceptual foundations of quantum field theory; philosophy of classic and quantum gravity; and axiomatization of thermodynamics and statistical mechanics. I am also interested in philosophy of mathematics, metaphysics, philosophical theology, and existentialism. My favourite film directors are Robert Bresson and Lars von Trier. My favourite writers are Mikhail Afanasyevich Bulgakov, Gabriel García Márquez, Albert Camus, Jean Paul Sartre, and James Joyce. I am also interested in the research of Catholic Liturgical Rites and philately. Before Pitt, I was an undergraduate student major in Physics at Peking University.
