Dr. Michael Berry is a Professor of Health and Exercise Science. Dr. Berry completed his undergraduate degree at Jacksonville State University in Alabama, his master's degree at Southeast Louisiana University, and his Ph.D. from Texas A&M University. Prior to coming to Wake Forest in 1985, Dr. Berry completed post-doctoral training at the University of North Carolina.  In addition to serving as chair, he teaches a statistics class at the graduate level and human physiology at the undergraduate level. Dr. Berry's early research interest was in the control of respiration during exercise which eventually led to his interest in the role exercise plays in the rehabilitation of those with lung disease.  Dr. Berry was the principal investigator on the two large randomized clinical trials funded by the National Heart, Lung, and Blood Institute that investigated how exercise can be used to improve physical and cognitive function in patients with chronic obstructive pulmonary disease (COPD) and how best to promote regular physical activity in these patients.  More recently, Dr. Berry's research has centered around improving function in intensive care unit patients with acute respiratory failure and the role that dietary nitrates play in improving function in pulmonary disease patients.
