Dr. Michael Rock completed a pediatric pulmonology fellowship at the University of Wisconsin-Madison from 1986 to 1989. During his fellowship, he became interested in the care of children with cystic fibrosis (CF) and became particularly involved with the Wisconsin Neonatal Screening Study. He was on the faculty of the University of Tennessee-Memphis for five and one-half years before returning to the University of Wisconsin in 1995. He was promoted to associate professor in 1997 and full professor in 2002.


In his current position at the University of Wisconsin, he is division head of pediatric pulmonology, director of the Cystic Fibrosis Center, director of the pediatric pulmonology fellowship and he chairs the CF Newborn Screening Advisory Group (Maternal and Child Health Section, State of Wisconsin). He served on the Cystic Fibrosis Foundation Center Committee from 2000-2004. This committee, consisting of CF Center Directors, is charged with formulating policy decisions for the care of CF patients in CF Centers and oversees centers through site visits.
