Interests: type IV collagen, autoimmunity, autoantibodies, basement membranes, Goodpasture disease, anti-GBM nephritis, Alport syndrome, hereditary nephritis

My lab studies the pathogenesis of inherited and acquired diseases involving type IV collagen, a major component of all basement membranes. In particular, the alpha3alpha4alpha5(IV) collagen network of the glomerular basement membrane (GBM) is centrally implicated in the pathogenesis of various forms of hereditary nephritis, including Alport syndrome, and is also the target of pathogenic auto-antibodies or allo-antibodies in anti-GBM antibody disease. The long-term objectives of our research are to elucidate the molecular mechanisms underlying the pathogenesis of these diseases in human patients and mouse models.
