.Katharina Wulff is the University Research Lecturer in chronobiology and sleep at the Nuffield Department of Clinical Neuroscience, University of Oxford. She studied biology at the Free University of Berlin and University of British Columbia, Canada.  In 2001, she completed her PhD at the Charite, Humboldt University Berlin in the field of human behaviour, chronobiology and sleep. Her work includes circadian adaptation during early human development, effects of ocular pathologies on sleep and circadian entrainment, and light exposure, photoreception and biological rhythm disruption in individuals with disorders of the brain such as psychosis and dementia. She has a long standing interest in communicating science, including links with architecture: ‘Living by the light of a glass house’ (2016/17) and school projects: BBC Terrific Scientific:Time Investigation (2016/17); Sleeping Sense : Composing Sleep (2015/16); Brain Awareness Weeks: Explore your Senses (2014/15); Museum Exhibition: ‘Sleeping Brain’ (2011); and Artlink: ‘Sun Dial : Night Watch’ 3 colourful tapestries highlighting seasonal and daily rhythms of behaviour and light exposure over an entire year, captured by wrist-worn sensors tracking light and activity every minute (2010-12).

Research Summary

The aims of our research are to elucidate the links between light exposure, circadian processes, sleep and emotions, to understand the function of timed light and sleep for mental well-being, and to define how such insight can be used for therapeutic interventions, application in LED lighting designs and architecture.
