Professor Fred Turek is the Director of the Center for Sleep & Circadian Biology and Charles & Emma Professor of Biology in the Department of Neurobiology at Northwestern University. He is also the founder and first President of the Society for Research on Biological Rhythms.

In this episode, we cover the basics of the “master clock” in the brain, and its control on downstream processes in the body via two well-known circadian rhythms - the sleep/wake cycle and the feed/fast cycle. We also talk about changing policy, and Professor Turek's involvement in the recent NASA Twins Study.

Enjoy!
