    Collapse Overview 
    Collapse overview
    My research is focused on 2 major areas:
    1. Cystic Fibrosis Liver Disease. I focus on clinical / translational research focused on identifying the underlying mechanisms of liver disease in CF, developing tests to identify liver disease in CF and to predict the subsequent development of advanced liver disease in CF using radiology, biochemistry and clinical predictors.
    2. Studies of the impact of CFTR modulator and corrector therapies on GI and liver manifestations in CF
    3. Clinical trials of antiviral therapy for chronic hepatitis B and C in children and adolescents.

    Cystic Fibrosis Foundations
    A Prospective Study to Evaluate Biological and Clinical Effects of Significantly Corrected CFTR Function
    Role Description: The goal of this study is to determine the biological effects of treatment with new highly effective CFTR correctors/modifers. Specifically to investigate the effect on hepatic fibrosis and liver disease as an embedded substudy
    Role: Substudy national Principal Investigator
