Christopher Oezbek's Homepage at Free University Berlin

I am no longer working at Freie Universität Berlin, but am a software engineer with medical technology company Scopis GmbH. Email: c.oezbek[at]gmail.com Workgroup: Arbeitsgruppe Software Engineering Office Hours / Sprechstunde Just stop by or make an appointment by email Feel free to ask me also questions about studying abroad (it's easier than you think) bachelor/master/diploma-theses which we are offering at AG Software Engineering competitions like the ACM Programming Contest if you want to achieve fame and glory or in general if you are interested in getting involved with scientific work Ph.D. Topic "Introducing Innovations into Open Source Projects" I have conducted a Grounded Theory study on the question of how to introduce software engineering innovations into Open Source projects. The work is empirical and studies 13 existing Open Source projects (from Bugzilla, KVM and Flyspray to MonetDB, ArgoUML, and U-Boot).
