Stuart Peirson

Professor Stuart Peirson leads the Circadian Neuroscience group at the University of Oxford's Sleep and Circadian Neuroscience Institute. His research examines how light regulates physiology and behavior, with focus on photoreceptor mechanisms, circadian rhythm entrainment, and the impacts of artificial light on health.

His laboratory combines molecular biology, genomics, and behavioral studies to understand light information processing from retina to brain. Recent work demonstrates how different melanopsin isoforms mediate behavioral responses to light and regulate both sleep-promoting and arousal-promoting pathways. Research trends include developing standardized light measurement protocols for animal research and investigating magnetic field effects on visual processing.

Key contributions include characterizing melanopsin signaling pathways in humans and identifying novel targets for regulating circadian rhythms and sleep. His group maintains active collaborations with clinical researchers studying light therapy applications.
