Biography

Manuel Spitschan is the Rudolf Mössbauer Assistant Professor of Chronobiology & Health at Technical University of Munich and Max Planck Research Group Leader at the Max Planck Institute for Biological Cybernetics. After undergraduate studies in psychology at the University of St Andrews (2009-2012), he completed his PhD on melanopsin sensitivity in the human visual system at the University of Pennsylvania (2012-2016). Following a post-doc at Stanford University (2016-2017), he joined the University of Oxford on a Sir Henry Wellcome Postdoctoral Fellowship, through which he collaborated with the Centre for Chronobiology in Basel (2017-2021). He is the current Speaker of the Steering Committee of the Daylight Academy, Chair of the Joint Technical Committee 20 of the CIE and past Chair of the Optica Color Technical Group.
