Field of Specialization

Inorganic reaction mechanisms with a focus on kinetic studies of substitution and redox properties of transition metal complexes; Inorganic synthesis with interest in catalysis and complexes of different biological activities.

Present Research

Syntheses and reactivities of transition metal complexes with particular interest in substitution and redox reactions involving Co(II & III), Ru(II & III), Pt(II), Pd(II), Au (III), Fe(II), Ni(II). These complexes are mostly coordinated to nitrogen based ligands like organoisocyanides, amines & diamines, pyrazoles, triazoles and tetrazoles among others. Such complexes have been known to have wide applications in catalysis and biological systems.  Working with colleagues with vast experience in computational and theoretical approach into solving chemical systems will provide a strong support to using kinetic and other physical experimental data in proposing and explaining the mechanisms of redox and substitution reactions of many transition metal complexes.
