I am an Associate Professor in the Theory Group in the Department of Physics. My research involves theory and simulation of nanomaterials. I am a developer of the ONETEP Linear-Scaling Density Functional Theory Package, which enables us to perform realistic simulations of large systems comprising thousands of atoms. This allows us to study complex systems such as proteins, heterostructure interfaces, layered materials, molecular crystals, and semiconductor nanocrystals.

I am a member of the UKCP Consortium, a High-End Consortium for access to the ARCHER supercomputer, and I am a member of the CCP9 Working Group, and PI of the current CCP9 Flagship Project. I am also a major user of Warwick's local HPC facilities, via the Scientific Computing Research Technology Platform, and the ATHENA system of the HPC Midlands Plus.

Current Projects

A large part of my work involves theoretical spectroscopy, specifically excitations in complex systems and interactions with the environment. I also have research interests across a wide variety of topics involving simulation of materials, particularly in relation to energy materials (eg OPVs, TiO2), layered materials (eg TMDCs) and biological systems (eg light-harvesting complexes).


I am always looking to recruit excellent students welcome and I enquiries from interested candidates, particularly those with a strong inclination towards theoretical and computational methods, and an interest in simulation of nanomaterials. I am interested in hearing from prospective PhD students, particularly anyone who might be candidates for schemes such as as the Chancellor's International Fellowships. Please contact me if you are interested, and also see the Prospective Students page.

Other Research

Please do contact me also if you have ideas of your own that are amenable to study with large-scale electronic structure methods!
