The overall focus of Dr. Ren's research is to improve and develop better tools to assess early lung disease in children and infants with cystic fibrosis. He studies advanced types of lung function testing and imaging, primarily magnetic resonance imaging. He is using a novel home-based app to remotely assess symptoms and changes a patient may experience while on highely effective CFTR modulator therapy. He also is interested in cystic fibrosis epidemiology, looking at outcomes using the cystic fibrosis patient registry, especially surrounding infants and newborn screening.

Dr. Ren came to Philadelphia from Riley Hospital for Children, Indianapolis, IN, where he was associate chief of the Division of Pediatric Pulmonology, Allergy and Sleep Medicine, director of the Cystic Fibrosis Center, and director of the Pediatric Pulmonary Function Laboratory.
