My primary domain of research is Variability Management and Software Testing. I am very interested in model based testing, testing of Software Product Lines, and Software Engineering in general.

For that purpose:

I was jointly responsible for the general workshop organisation of the 1st International Workshop on Model-Driven Product Line Engineering (MDPLE09)  held in conjunction with European Conference on Model-Driven Architecture (ECMDA) Twente, The Netherlands, June 24th, 2009

I was Chair of the 1st International Workshop on Requirements and Validation, Verification & Testing (ReVVerT2010) held in conjunction with the 4th IEEE International Conference on Software Testing, Verification, and Validation (ICST) Berlin, Germany, 2011.

I was a member of the Program Committee of the 4th Workshop "Produktlinien im Kontext" (PIK2010) held in conjunction with the National Conference "Software Engineering", Karlsruhe, 2011.

I was a participant at the Dagstuhl Seminar "Feature Oriented Software Development" (FOSD), 2011.

I am a member of the Program Committee of the 3rd International Workshop on Model-driven Approaches in Software Product Line Engineering (MAPLE2011) held in conjunction with the International Software Product Line Conference 2011 in Munich.
