Senior experimental psychologist John Caldwell has spent the bulk of his career researching the effects of sleep deprivation and sleep restriction, while also studying countermeasures that sleep-deprived people can use to function better. Much of his research was conducted within the military aviation community, and it helped fuel insights for the book “Fatigue in Aviation: A Guide to Staying Awake at the Stick,” which he co-wrote with J. Lynn Caldwell.
