The theoretical methods of quantum chemistry have matured to the point that accurate predictions can be made and experiments can be understood for a wide range of important gas-phase phenomena. A large part of this success can be attributed to the maturation of hierarchies of approximation, which allow one to approach very high accuracy, provided that sufficient computational resources are...

Biography

Frederick R. Manby is a Reader in the Centre for Computational Chemistry in the School of Chemistry at the University of Bristol, and was previously a Royal Society University Research Fellow. His research has focused on two main areas: first, on the development of efficient and accurate electronic structure methods for large molecules. Second, he has worked on the accurate treatment of condensed-phase systems, including electron correlation in crystalline solids, and on the application of wavefunction-based electronic structure theories to molecular liquids, particularly water. Dr. Manby was awarded the Annual Medal of the International Academy of Quantum Molecular Sciences (2007) and the Marlow Medal of the Royal Society of Chemistry (2006) in recognition of his research on molecular electronic structure theory.
