Our biology is governed by a 24-hour biological (circadian) clock that advises us when it is the best time to sleep, eat, think, and undertake a myriad of other essential tasks.

Progress in understanding the fundamental nature of circadian biology has been astonishing, and this knowledge has added to our wonder and appreciation of the biological world.

However, with this appreciation comes an emerging realisation of how essential circadian rhythms are to our health and wellbeing.

Professor Russell Foster is the Head of Oxford’s Nuffield Laboratory of Ophthalmology, the founder and Director of the Sleep and Circadian Research Institute and is a Fellow of Brasenose College Oxford.

His research addresses how circadian rhythms and sleep are generated and regulated and what happens when these systems fail because of societal pressures, ageing and disease.
