Brief description of current research:

My lab focuses on the biology of cystic fibrosis (CF) and the development of new treatments for the disease. I am interested in the actions of cystic fibrosis transmembrane conductance regulator (CFTR), the anion channel that is disrupted in CF, and how its loss influences the pathogenesis of CF. By middle age, over 50% of people with CF develop diabetes mellitus. Thus, CF provides significant opportunity for insight into diabetes pathogenesis.
