I am the technical director of the SleepLoop HMZ Flagship responsible for all technical innovations of SleepLoop.

SleepLoop is a wearable sleep monitoring and stimulation system developed at the Universities of Zurich (ETH Zurich and University of Zurich). The aim of SleepLoop is to enhance health by using mobile technologies that improve and deepen sleep in various stages of life from childhood to old age. SleepLoop enables large scale research outside of the lab and will support all people that need deeper and a more regenerative sleep.

SleepLoop has been awarded the Hochschulmedizin Zurich Flagship Award 2018-2021.
