The Matthews group focuses on using and developing accurate theoretical methods to study molecules, reactions, clusters, and extended systems. In particular, the emphasis is on ab initio (meaning "from the beginning") methods based on quantum mechanics, combining concepts and techniques from chemistry, physics, mathematics and computer science. Specific active research areas include computational spectroscopy, especially in the X-ray region, computational techniques for tensor contraction and factorization, and development of new theoretical methods related to and inspired by the coupled cluster family of methods.
