Guido Bacciagaluppi Guido Bacciagaluppi was born in Milan in 1965. After obtaining his degree in mathematics from ETH Zurich and his doctorate in philosophy from the University of Cambridge, he was Research Fellow at Wolfson College, Cambridge, and at Balliol College, Oxford. He was Junior Lecturer at Oxford University, Assistant Professor at the University of California at Berkeley, as well as Humboldt Fellow at the University and the IGPP of Freiburg (Germany). He then worked at the IHPST, Paris, before joining the Centre for Time in November 2006. His work is mainly on the philosophy of physics, in particular the foundations of quantum mechanics. His interests range from the more technical subfields (pilot-wave theory) to the more speculative ones (Everett's many-words). He has contributed significantly to the development and critique of modal interpretations of quantum mechanics. More recent interests include the direction of time and probability, as well as their relation to quantum mechanics. He is currently working (with A. Valentini) on a commentary and English translation of the Proceedings of the Fifth Solvay Congress (1927), a rather more historical project. Guido is also subject editor in quantum mechanics for the Stanford Encyclopedia of Philosophy.
