Russell Foster is Professor of Circadian Neuroscience and the Head of the Department of Ophthalmology at Oxford University. His research spans basic and applied circadian and photoreceptor biology. For his discovery of non-rod, non-cone ocular photoreceptors he has been awarded the Honma prize (Japan), Cogan award (USA), and Zoological Society Scientific & Edride-Green Medals (UK). He has also written several books, such as Rhythms of Life , co-authored with Leon Kreitzman (Profile Books, 2004) and Sleep: A Very Short Introduction (Oxford University Press, 2012).Leon Kreitzman is an esteemed author, biologist and broadcaster who is currently a visiting consultant at the Nuffield Health Centre at Oxford University. He has written numerous articles and books on the social and scientific factors of chronobiology, including The 24 Hour Society (Profile Books, 1999).

Circadian Rhythms is an ideal companion to Sleep, another excellent book in the same series and co-authored by Foster ... Foster and Kreitzman delve into the molecular biology that underlies the circadian rhythms, but they do so clearly and gradually. So even if you're not a biologist you'll be able to follow the discussions.
