Dr. Pamela Zeitlin is a professor of pediatrics and physiology at the Johns Hopkins University School of Medicine. Her area of clinical expertise is in pulmonary medicine, with a particular focus on cystic fibrosis. She serves as the director of pediatric pulmonology and the co-director of the Cystic Fibrosis Center at the Johns Hopkins.

Dr. Zeitlin received her M.D. and Ph.D. degrees from the Yale University School of Medicine, completed her internship and residency in pediatrics at The Johns Hopkins Hospital and her fellowship in pediatric pulmonology at Johns Hopkins University School of Medicine.

In 1988, she joined the Johns Hopkins faculty in pediatrics, where she has developed a program of clinical and translational research into cystic fibrosis. Dr. Zeitlin directs a pediatric pulmonology multidisciplinary training grant for Ph.D. and M.D. trainees interested in developing an academic career in respiratory research. She is director of the Eudowood Division of Pediatric Respiratory Sciences and deputy director of the Institute for Clinical and Translational Research at Johns Hopkins University. Her research focuses on the role of chloride channels in inherited diseases of the respiratory tract, e.g., cystic fibrosis. 

She serves on a number of National Institutes of Health Studies Sections and is a member of the American Thoracic Society. more

Research & Publications

Research Summary

Dr. Zeitlin’s research focuses on the role of chloride channels in inherited diseases of the respiratory tract. Her particular focus is on cystic fibrosis.  She has studied cystic fibrosis treatments in animal models, developed a cystic fibrosis cell line that’s now shared around the world and participated in a number of studies evaluating an array of novel treatments, including ivacaftor.


Dr. Zeitlin’s lab is studying the role of chloride channels in inherited disease of the respiratory tract. Her focus is on cystic fibrosis where she has cloned uses animal models to understand the contribution of chloride transport in developing lungs and in disease.
