I am a research associate at the University of Hagen, digital transformation enthusiast and experimental psychologist with interest in programming and data science. My research focuses on how we act together in a digital world: with robots, with AI, with our virtual avatars. As a fortunate (young) father, start-up co-founder and researcher I like optimizing processes in respect to mental well-being and everyday-life-challenges - UX and Human-Centered-Design is a universal approach to every hindrance in life.

My work orientates itself around the intersecting point of psychology and information technology. Understanding Joint Action in a Digital World will be crucial for the upcoming development in e.g. AR and VR. How is interacting with the digital world comparable to interacting in the real world? Has a computer partner the same quality as an human partner. Furthermore, I am focused on using open-source-software-based solutions to tackle common problems of human-machine interactions: Getting data, understanding user behavior, and finding new technology-aided approaches to problems of today’s digital and cognitive challenges emerging from interacting without physical presence or with non-human co-actors.
