Luka Biedebach

Luka Biedebach first joined the Sleep Revolution in 2021  to write her master thesis on identifying paediatric mouth breathing during sleep. During this time, she created an unsupervised reconstruction-based anomaly detection model that classifies breathing sequencesShe then graduated from the University of Mannheim with a Master Degree in Data Science. Exploring all the possibilities of applying machine learning in sleep research raised her interest to dive deeper into this field.  

 

In 2022 she came back to Reykjavik University as Ph.D. Candidate within the Sleep Revolution. Her research focus is on unsupervised machine learning in sleep research. In her PhD thesis, she explored different sleep data types, as well as different unsupervised learning methods. She defended her PhD in April 2025 and is now working as a Postdoctoral Researcher at Reykjavik University.
