His main research interests are in the area of renal tubulointerstitial fibrosis, inflammation and also the mechanisms of renal cancer development – particularly the role that cytokines and growth factors play in these processes. Current projects include the role of protease activated receptor-2 in renal scarring, inflammation and cancer, the mechanism of heavy metal toxicity in the kidney and the renoprotective properties of erythropoietin.
