Research

  • Goal: My longterm research goal is to (1) understand user behavior and to invent AI that is able to simulate and predict user behavior accurately and (2) to develop novel AI methods (algorithmically or from an HCI perspective) that are able to change and positivly infuence user behavior through, for example, recommender technology, to help people to implement a more healthy news or food diet.
  • Approach: I would position my approach to research in the intersection of qualitative and quantitative research design with heavy theoretical underpinning from various fields e.g. economy, psychology, physics or medicine. As such I drive small to large-scale offline studies through e.g. empirical analysis or simulations, living lab studies or large-scale online experiments utilizing the wisdom of the crowd, to explore new patterns, to validate algorithms or models or to validate certain theoretically underpinned hypotheses or research questions.
  • Application: In general my work has applications to many domains, but typically where a large number (potentially millions) of users directly or indirectly interact with each other, and where their collective cognitive output needs to be analyzed, modeled, predicted or changed.
