Professor David DeutschDepartment Clarendon Laboratory 
Research InterestsFundamental aspects of physics, especially the foundations of quantum theory and the quantum theory of computation. Also constructor theory (a putative new field, more closely related to quantum theory than to von Neumann's constructor theory).
