Principal research interests have been in the areas of biochemical mechanisms of nephrotoxicity, particularly of paraquat, and of analgesics, trimethoprim, sulphamethoxizole, lithium, aminoglycosides, Cyclosporin A and paraquat. The clinical and basic functional aspects of renal transplantation and other aspects of Cyclosporin A have also been investigated.
