Research Interests & Projects
Noncovalent Interactions in Chemistry and Physics
Noncovalent interactions play a central role in determining structure and reactivity throughout chemistry and physics. Our group develops and applies computational methods to understand this role. We are also currently editing a book entitled “Noncovalent interactions in quantum chemistry and physics: Theory and application”, which was published by Elsevier in 2017. The book features contributions from some of the world-leading researchers in the field.
Our most recent research work in this area focussed on the development of very computationally efficient methods, based on effective core potentials, that allow us to model large systems of biochemical relevance, like proteins and enzymes.
Radicals in Chemistry and Physics
We are using computational chemistry techniques to study a wide variety of radical systems in chemistry, biochemistry and physics. Our current research focusses on quantum effects in enzymes that mediate radical rearrangement processes and on the potential for non-redox metal cations to act as a chemoprotective against radical damage through hydrogen atom transfer reactions. We are also working with device engineers to understand how radical species can be used in nanoscale molecular junction devices.
