College of Health and Human Sciences 21 Jul, 2021 Barry Braun, health and exercise science professor and executive director of the Human Performance Clinical Research Lab, prepares to rappel off a 60-foot tower in Fort Knox, Kentucky. Barry Braun has an interesting story to share when his students return for fall classes at Colorado State University. The health and exercise science professor and executive director of the Human Performance Clinical Research Lab rappelled off a 60-foot tower in Fort Knox, Kentucky. It was all part of the Army ROTC Cadet Summer Training Leadership Symposium in June. Braun was one of a select few to participate in the symposium’s Center of Influence, in which more than 200 universities compete for representatives.
