During my doctoral research, I investigated the concept of Software Resilience in the domain of Software Engineering and more specifically in the Open Source Software realm. The research is reflected in a Resilience Framework for Open Source Software Assessment, published by Wiley to the Journal of Software: Evolution & Processes.

The full text of my Doctoral Dissertation is available here. If you are looking for a summary of the ~140-page document, you can browse through the following SpeakerDeck presentation:
