Our research focuses on digital and connected approaches to improving the quality of life of individuals with cognitive impairment. A key area of work is the development of digital interventions to promote health-related lifestyle changes. These include, in particular, chatbot-based applications and Just-in-Time Adaptive Interventions (JITAIs), which provide personalized support in everyday life and foster long-term adherence. In addition, we investigate telemedical approaches as well as real-world sensing and monitoring technologies that enable low-threshold diagnostics, allow early detection of changes, and contribute to the prevention of unnecessary hospitalizations. Furthermore, we examine motivational mechanisms that facilitate and sustain behavior change over time, with a particular focus on self-efficacy, subjective well-being, and coping with neurodegenerative diseases. A central, overarching component of our work is the development and application of structured evaluation pipelines for digital health applications. These enable us to systematically and evidence-based assess effectiveness, usability, and implementability across the entire development process. Our projects are conducted in close national and international collaboration with clinical, academic, and technological partners and are embedded within larger research networks.
