I'm a theoretical physicist, specializing in quantum mechanics, gravitation, cosmology, statistical mechanics, and foundations of physics, with occasional dabblings elsewhere. This site contains information about me, including research and my CV, plus news, books, videos, and other activities. My newest book, Something Deeply Hidden, is about quantum mechanics, Many Worlds, and the emergence of spacetime; it will be released on 10 Sept. I recently started a podcast, Mindscape, where I interview smart people about interesting ideas.
My official title is Research Professor of Physics at Caltech. I live in Los Angeles with my lovely wife, science writer Jennifer Ouellette.
