Research Interests

Reduction of potentially toxic oxoanions by kinetically active cellular and non-cellular substrates.

Stereoselectivity in Biomolecular Reactions Involving Metal Ion Complexes.

Molecular Mechanics(MM) and its uses in the study of structural aspects of ligand systems and complexes of main group and transition metal ions.

The search for potentially useful novel bimetallic and trimetallic systems.

The mediatory role of dissolved molecular oxygen in redox reactions with particular emphasis on amino acids, vitamins and small molecular weight substrates of biological interest.
