The research programs in the Division of Pulmonary and Sleep Medicine reflect the broad range of interests of the group. Researchers have participated in the Wisconsin Cystic Fibrosis Newborn Screening Project since 1985. Dr. Hara Levy has funding from the National Institutes of Health (NIH) to investigate gene modifiers’ role in disease severity in children with cystic fibrosis. Other research involves acquisition of pseudomonas aeruginosa in children with cystic fibrosis and use of azithromycin as an anti-inflammatory agent in children with cystic fibrosis. In the sleep program, investigators have looked at mechanisms of upper airway obstruction in children with obstructive sleep apnea and management of upper airway obstruction with mandibular distraction in children with Pierre-Robin syndrome. Dr. Thom Feroah has funding from NIH to investigate the genomic basis of sleep disorders. Finally, investigators are looking at the epidemiology of rural asthma.
