Electronic Structure Studies in Chemistry and Materials

My classical research field is Computational Inorganic Chemistry.  I specialise in the application of electronic structure methods (Density Functional and Wavefunction approaches) to understand chemical transformations at the molecular level.

The focus has been on making new inroads in the design of catalysts for sustainable energy production, the creation of novel chemical species with desirable properties, or to understand the origin of electronic properties such as magnetic bistability in transition metal complexes.

Computational chemistry is eclectic and I have made forays into photo- and electro-chemistry, gas phase chemistry, heterogeneous catalysis, homogeneous catalysis, magnetochemistry and spectroscopy.

Present Research interests:

The key actions which I am currently pursuing or intend to pursue in association with experimental partners are the following:

1) Life sciences (e.g. biomimetic chemistry, enzyme action)
2) Environmental custodianship (CO2 activation and storage; molecular metal oxides as environmentally friendly catalysts; actinide chemistry)
3) New materials for IT (magnetic switching, data storage).
