Research Interests

Research is directed towards using the properties of the carbon―fluorine bond in organometallic chemistry and for highly repellant surfaces.

Organometallic Chemistry
The extreme strength and the electronic and steric properties of the C―F bond are used to confer useful properties on organometallic complexes, in particular catalytic activity.
C―F bond fission is used to synthesize organometallic complexes, not accessible by other routes.
Superhydrophobic Surfaces
The extreme water repellancy of perfluoroalkyl groups is used to confer superhydrophobicity on metal surfaces. The work has been highlighted by Nature and Scientific American. The simple fabrication technique allows a range of unusual phenomena to be investigated, such as the Cheerios Effect and 'super-buoyancy', which allows boats to be constructed of metal mesh, and has potential industrial importance.
