Bryan W. Roberts is a philosopher of science at the London School of Economics and Political Science. His research deals with the philosophical and mathematical foundations of modern physics. He likes to think about the conceptual underpinnings of our best theories of fundamental matter, the concept of "time reversal" by which modern physics distinguishes between the past and the future, classical and quantum time observables, the history of physics, and the relationship between quantum mechanics and other scientific theories. His Ph.D. in History and Philosophy of Science was from the University of Pittsburgh in 2012. He held the Provost's Postdoctoral Fellowship at the University of Southern California in 2012-2013, before becoming a Lecturer in the Department of Philosophy, Logic and Scientific Method at the LSE. He lives in London with his wife Alma C. Roberts.
