Research Projects

  • Establishing personal trust-based connections in distributed teams
    Trust is a factor that dramatically contributes to the success or failure of distributed software teams. We investigate how social communication between distant developers enables the affective appraisal of trustworthiness even from a distance, thus increasing project performance.
  • Success factors in online creative communities
    The project aims to identify the fundamental resemblances and differences between the open source software (OSS) communities and creative arts communities and propose solutions to improve the latter, building a better user experience and cohesion within the community that could lead to better artifacts.
  • A Hub-and-Spoke Model for Tool Integration in Distributed Development
    Today, an ever-growing plethora of development tools provide a continual stream of updates and place developers into a situation of channel overload and information fragmentation. This project defines a model for the loosely-coupled integration of development tools, which can help developers cope with these issues while also increasing their overall situational awareness.
