Stuart Phillips, PhD, is a professor of kinesiology at McMaster University in Hamilton, Ontario, Canada, where he also serves as the director of the Physical Activity Centre of Excellence. His research centers on the roles exercise and nutrition play in influencing human skeletal muscle protein turnover and how these lifestyle factors influence body composition, especially as we age.
