Research Interests

My research focuses on the physicochemical and biochemical risk factors associated with the formation of kidney stones. This research area lends itself very well to initial computer modelling followed by laboratory investigation because the fundamental laws of physical chemistry pertaining to solubility, saturation, supersaturation, chemical kinetics, chemical equilibrium, precipitation and crystallization, are appropriate. Application of these concepts in crystallization processes in urine provides insights into the physicochemical factors which influence stone initiation and growth and gives direction for the development of treatment protocols.   My research investigates conservative dietary and supplemental interventions for reducing the risk of stone development. Nutrients and supplements of interest are polyunsaturated fatty acids, phytate, mineral waters, pomegranate, green teas, vitamin E, and traditional herbal dietary agents and stone medications.

Although stone disease occurs in the white population to the same extent as elsewhere in western societies, it is rare in the black population. Investigation of this phenomenon is another research focus of mine.

I have successfully supervised 30 MSc and PhD students in this field.
