Dr. Oster studied biochemistry at the Leibniz University of Hanover from 1993 to 99 and received his doctorate for studies of molecular circadian clocks from the University of Fribourg in 2002. After postdoctoral research at the Max Planck Institute for Experimental Endocrinology Hannover, the University of Oxford and the Max Planck Institute for Biophysical Chemistry in Göttingen, he joined the University of Lübeck as Lichtenberg Professor of Chronophysiology in 2011. Since 2017, he heads the Institute of Neurobiology and in 2018, he was appointed as the first Lichtenberg Endowed Chair of Neurobiology. His research covers the function of circadian clocks and their impact on health with a focus on the endocrine system and metabolism. He serves as senior editor of Endocrine Connections and Nature Scientific Reports, associate editor of Frontiers in Molecular Neuroscience, and as editorial board member of PLoS ONE, Journal of Circadian Rhythms and Journal of Exercise Rehabilitation.
