The QoL lab research interests revolve around the fundamental and algorithmic problems as well as human-centric challenges for the systems enabling an assessment and improvement of human behavior, well-being, health, disease self-management, and quality of life in the long term. The QoL Lab leverages personal, longitudinal, real-world data approaches (including, e.g., ‘quantified-self’ and N-of-1 designs) in Living Lab settings.
