Current projects

I am interested in all aspects of theoretical and computational chemistry, but especially quantum chemistry. I have close links with Professor Mark Spackman and Dr Ben Correy.
My main interest now is in deriving electronic wavefunctions from scattering experiments, such as the X-ray diffraction experiment, the polarised nuetron diffraction experiment, the electron diffraction experiment, and the (e,2e) scattering experiment. The basic idea is to derive wavefunctions that exactly reproduce the results of these experiments, for more accurate modelling. Currently, in collaboration with Professor Spackman, I am interested in calculating refractive indices and non-linear optical properties for molecular crystals.
I am also interested in developing new quantum chemical calculation methods, including new methods for open shell systems, new non-orthogonal determinant methods, new integral methods, and new methods for solid state quantum chemistry. These methods will extend the type of calculations that we can do.
I am also interested in visualization and graphics. We have also developed a graphical user interface called "Crystal Explorer" for displaying and manipulating crystal structures and "Hirshfeld Surfaces". These surfaces can be used to enhance our understanding of crystal packing in molecular crystals and it has become very popular. Below is an interactive picture showing various colour coded functions mapped onto a Hirshfield interface for 3-amino phenol.
