    Research Summary

    Dr. Racusen’s research focuses on injury to the kidney, morphologic aspects of native kidney and renal allograft injury and rejection, utilizing in-house biopsies and consultant cases, and computerized morphometric techniques.

    She and her team are currently studying pathologic correlates of antibody-mediated rejection, assessment of chronic changes in renal allografts, and urinary molecule markers of renal allograft rejection. They are also collaborating with colleagues in nephrology to characterize animal models of acute and chronic renal injury.
