Sandu Popescu is Professor of Physics at the University of Bristol, UK. Between 1996 and 2008 he was also associated with Hewlett-Packard Laboratories in Bristol. He is one of the world's foremost experts in the field of Quantum Information theory, and also in the foundations of quantum mechanics. His research interests center on fundamental aspects of quantum physics, in particular gaining a better understanding of the nature of quantum behavior. A major focus of his research has been quantum nonlocality. This led him to establish some of the central concepts in the area of quantum information and computation. Dr. Popescu has also worked on many other aspects of quantum theory, ranging from the very fundamental, to designing practical experiments (such as the first quantum teleportation experiment), to patentable commercial applications. He was awarded the Adams Prize in 2000 for contributions to quantum information.
