I am a pediatric physician-scientist striving to advance cystic fibrosis clinical care and translational research. Clinically, I am focused on gastrointestinal manifestations of cystic fibrosis, developing diagnostic and therapeutic modalities to improve the gastrointestinal and liver health of those with cystic fibrosis. I also specialize in the clinical management of pediatric pancreatitis and am involved with the international INSPPIRE consortium to study pediatric pancreatitis. My research spans the entire spectrum across basic science and translational research to clinical research and trials. In the laboratory, my projects are centered around understanding mechanisms of ion transport in cystic fibrosis tissues and determining how loss of CFTR ion transport leads to pathologic changes in human physiology. We are also very interested in the pathophysiological relationship between pancreatitis and intestinal diseases, such as inflammatory bowel disease. Our laboratory has expertise in epithelial ion transport, with specialized skills in the measurement of bicarbonate transport. We are also part of a Multi-PI collaboration pursuing CFTR gene editing and stem cell engraftment for the treatment of cystic fibrosis. We utilize a combination of immortalized and primary cell culture, organoids, mouse and human tissue, and whole animal in vivo studies.
Deficient bicarbonate secretion contributes to the hyperviscosity of mucus in CF airways and intestines, and contributes to poor nutrient absorption. We are studying CFTR-independent mechanisms of bicarbonate secretion in CF intestines and airways in order to identify novel therapeutic targets for cystic fibrosis.
