Dr. Marie Egan

Biography

Dr. Egan specializes in pediatric pulmonology, focusing on treating children with cystic fibrosis and related respiratory conditions. She is dedicated to improving the lives of young patients by addressing issues of mucus clearance, infection management, and lung function preservation. Her interest in cystic fibrosis began at age 18 when she volunteered at a children's hospital, where she was inspired to pursue a career that combined her love for science with her desire to assist children facing health challenges. As a professor of pediatrics and cellular molecular physiology at Yale School of Medicine, Dr. Egan studies how ion channels can disrupt the body's ability to clear mucus from the lungs, leading to breathing difficulties and infections in diseases like cystic fibrosis. Her lab focused on the CFTR protein, which is faulty in cystic fibrosis, and how it influences ion channels affecting lung health. Dr. Egan is working on gene editing projects aimed at correcting genetic mutations in the CFTR gene, with hopes of developing new treatments. She takes pride in the impact she has had on patients and considers it a significant honor to help those navigating chronic illnesses.
