This inaugural seminar of the TORCH network “Sleep and the Rhythms of Life” features Russell Foster, Head of the Sleep and Circadian Neuroscience Institute at the University of Oxford and author of Life Time (Penguin, 2022), and Ian Ritchie, the architect who created spectacular buildings such as the Sainsbury Wellcome Center at University College London (pictured on the poster). From different yet connected disciplinary perspectives, Russell Foster and Ian Ritchie cut to the heart of how light impacts sleep and architectural practices.
