    • About Me

    I am involved in various research projects on a fundamental and applied research level. Before moving to Finland, I completed a PhD project at the TU-Eindhoven in the Netherlands and a member of the BETA research school. My PhD was embedded in the EU research project called CrossWork. In CrossWork we focused on distributed, cross-organizational development processes in the automotive industry, forming Networks of Automotive Excellence (NoAE). The main project objective was the development of mechanisms for automated workflow formation and enactment, enabling NoAE. Our technological approach was based on Multiagent Systems (MAS), introducing the paradigm of distributed & decentralized decision making in Workflow Management Systems (WfMS) Currently, I work on a Cloud Computing project.

    Past Background

    Studies: Business Informatics, Management Science
    Universities: University Linz, UMIST, Hagen, TU-Eindhoven
    Past Work Places: As a student assistant at the DKE, as a
    research assistant     at the IFS for
    PSE SIEMENS     Vienna, and later as a
    PhD researcher     at the IS department of TU/e.
