Some significant leadership changes are taking place at East Carolina University. Dr. Michael Lewis is being replaced as ECU's Vice Chancellor for Health Sciences. That move was one of several announced by Chancellor Steve Ballard Monday. Dr. Cynda Johnson is also being replaced as Dean of the Brody School of Medicine. The two are being transitioned to other ECU positions. Officials say the changes are all part of an effort announced earlier this year to make ECU Physicians financially sound. ECU Physicians is a group of faculty members that offers medical care and services to the community. Officials say the group has lost $25,000,000 over the past six years. Dr. Phyllis Horns, longtime Dean of the School of Nursing, has been named interim Vice Chancellor for Health Sciences and interim Dean of the Brody School of Medicine.
