We just concluded the first Lullabyte Training camp which happened from 16.-20. September 2023 at the Donders Institute at RadboudUMC in Nijmegen. We had five days full of lectures, workshops and worksessions focusing on methods of sleep research and creative interdisciplinary research. For the Lullabyte PhDs it was the first meetup in person since the start of the network. Everyone is now eager to continue.
