Every day we suffer from sleep loss, circadian disruption, and sleep disorders that take their toll on us as individuals, organizations, and society. Ignoring the risks of our 24/7 world affects everyone. We neglect our biological clocks at our own peril. Former NASA scientist and fatigue management expert Mark Rosekind presents ways to improve sleep and alertness that can significantly boost your productivity, safety, and health.

Mark R. Rosekind, PhD, is co-founder of Alertness Solutions in Cupertino, California. He is internationally recognized for translating scientific knowledge on sleep, circadian factors, human fatigue, shiftwork, performance, and alertness into practical strategies that improve safety and productivity in our round-the-clock society.

Dr. Rosekind was a research psychologist, principal investigator, and team leader with the Fatigue Countermeasures Program in the Flight Management and Human Factors Division at NASA Ames Research Center from 1990 to 1997. He received an undergraduate degree from Stanford University, a PhD from Yale University, and postdoctoral training at Brown University. In 1995 he was awarded the NASA Exceptional Service Medal, and has also received a Flight Safety Foundation Presidential Citation for Outstanding Achievement in Safety Leadership and a NASA Group Achievement Award.

In 1999, Dr. Rosekind was a Fellow at the World Economic Forum in Davos, Switzerland. Before his NASA work, he directed the Center for Human Sleep Research at Stanford University's Sleep Disorders Center.
