Research Interest

Our research interest is in organometallic chemistry and its applications in a number of different areas:

Bioorganometallic chemistry
Bioorganometallic chemistry lies at the confluence of organometallic and biological chemistry. Current activities in this new field are already very wide-ranging and varied. Our own interest is in the application of organometallic carbonyl clusters in particular, in the biomedical areas and in biology.

Nanoscience
Nanomaterials are finding increasing utility in a number of areas, including biomedical imaging and heterogeneous catalysis. Control of their size and composition are very important, and organometallic compounds, in particular organometallic clusters, are useful precursors for this purpose.

Homogeneous catalysis and bond activation
The link between organometallic chemistry and catalysis, especially homogeneous catalysis, is well established. Our current interest in homogeneous catalysis lies mainly in bond activation reactions and a detailed study of the reaction pathways utilising spectroscopic, kinetic and computational methods.
