Field of Specialisation

My research interests are broadly centred on the design, synthesis and characterisation of organometallic complexes with specific biological application (such as in anticancer treatment) and also I am involved in the design of the transition metal complexes that are relevant in catalysis. Typical characterisation techniques include Nuclear Magnetic Resonance (NMR), X-Ray Crystallography, Fourier-transform Infrared Spectroscopy (FTIR), Ultraviolet–visible Spectroscopy (UV-vis), Scanning Electron Microscope (SEM) and X-Ray Powder Diffraction (XRD), Potentiometry and HYPERQUAD.

 

My other areas of interest include the use of the hydrometallurgical process for the recovery of various base metal (such as nickel, iron, zinc, and copper) from ores.
