Research Focus


My research focuses on diseases of the renal glomerulus (the filtering unit of the kidney), especially those initiated by immunological processes ("glomerulonephritis"). These diseases account for approximately half of the causes of chronic kidney disease in Canada. Fundamental research into the disordered immune mechanisms that lead to glomerulonephritis is essential to the understanding of these diseases, an understanding that will ultimately lead to therapy and perhaps prevention. My research is directed at understanding pathophysiological changes in kidney cells in immunological disorders and inflammation. Work in the lab focuses on signals in cells that are involved in the mediation of cell injury. There are three specific research themes, including: complement C5b-9 signaling and mechanisms of injury, extracellular support structures and cell skeleton as determinants of signaling responses, and regulation of intracellular proteins that mediate signals in the kidney.
