how to relate the mathematics to the real world is incomplete". It is this application of quantum information to the real world that Griffiths strives for. In 1984, he initiated a research program which sought to supply the missing link between theory and application while working out an entirely consistent form of quantum theory. Along with contributions of several key colleagues, the project eventually resulted in what is now commonly called the consistent (or decoherent) history approach to quantum theory, now effectively studied and applied in several areas of the field of quantum mechanics. At present, Griffiths is the Otto Stern University Professor of Physics at Carnegie Mellon University. He has published over 140 articles, as well as the book Consistent Quantum Theory. He is a member of Sigma Xi, a Fellow of the American Physical Society and a Fellow of the American Scientific Affiliation. Griffiths' research interests continue to include the foundations of quantum mechanics, quantum computation, and the relation of physical science and Christian theology.
