Dr. Stoltz is Director of the CFF RDP and an NIH PPG studying the pathogenesis of CF lung disease in CF pig models. His areas of research include the roles of CFTR in smooth muscle, and CF disease pathogenesis involving goblet cell functions, innate immunity, and inflammation. Recently, Dr. Stoltz developed in vitro organoid models of the gallbladder from CF pigs, ferrets, and humans, which his group uses to study how CFTR function influences pH regulation and mucin secretion in this organ.
