I am a Visiting Professor of physics at the Centre for Quantum Computation, the Clarendon Laboratory, Oxford University and an Honorary Fellow of Wolfson College, Oxford. I work on fundamental issues in physics, particularly the quantum theory of computation and information, and constructor theory.

I have written two books – The Fabric of Reality and The Beginning of Infinity – aimed at the general reader.

Some thinkers I admire: Karl Popper, Michael Faraday, William Godwin, and Richard Feynman.
