Russell Foster is a renowned researcher in circadian and sleep neurobiology with a long-standing focus on how light regulates circadian rhythms in vertebrates. His primary research has been on the molecular mechanisms underlying light regulation of the mammalian circadian clock. More recently, he has broadened his research to include a mechanistic understanding of sleep and circadian rhythm disruption across the health spectrum, particularly in eye disease, mental illness and aging. Dr. Foster is a pioneer in the field, having discovered a third class of retinal photoreceptors in the mammalian eye. This groundbreaking discovery has been recognized by multiple prestigious awards, including: The Honma Prize (Japan), Cogan Award and Peter C. Farrell Prize (USA), Edridge Green Medal and Zoological Society of London’s Scientific Medal (UK), Holst Medal (The Netherlands), Sourkes Memorial Prize (Canada), Feldberg Prize (Germany) and Daylight Award for Research (Denmark).
