Computational methods to analyze and support human collaboration

I employ artificial intelligence (AI) to study and support collaboration in organizational settings, open source communities and time-bounded events such as hackathons. Related to organizational settings, I utilize machine-learning to analyze collaboratively created artifacts such as process models to provide automated feedback about the current collaboration state in a workshop setting. In the context of open source, I employ AI driven analytics to study the tenure of contributors on GitHub utilizing socio-capital theory as a lens. With respect to hackathons, I focus on fostering their impact beyond singular events organized in a specific context. To that end I use a mixed method approach conducting qualitative case studies to identify individual and team related aspects that are associated with the sustainability of hackathon outcomes in the context of corporate, entrepreneurial and scientific events before utilizing quantitative methods, such as big data analytics, to identify quantitative factors that indicate project continuation. Based on these studies I have developed a multi-level methodological open-source framework to help hackathon planners navigate design decisions to make their event a success (hackathon-planning-kit.org). I am currently working to expand this framework towards online and hybrid settings by adding socio-technical support for hackathon organizers and participants.

Socio-technical collaboration support

In this area I study and develop systems that facilitate human-vehicle interaction in the context of autonomous vehicles. Focusing on the aspect of trust from a planned behavior perspective I conduct studies with systems in a ride-hailing context that cover the vehicle approaching the user, allowing the user to control various parameters during the ride and the user disembarking. I also co-develop RuM (rulemining.org), an open source toolkit for analysts that utilizes AI to visualize (business) processes based on event logs and that provides advanced analytics to identify issues and bottlenecks.
