Research

My main area of research interest is currently Cloud and Service Systems Engineering.The central objective is the development and application of software engineering technologies for dependable software and information systems - combining classical software engineering techniques with domain-specific solutions - for cloud and service architectures in particular. Software architecture is the central perspective. Model-driven development provides the methodological context. The systems engineering perspective, addressing a holistic perspective of software and the systems environment it is embedded in, is of particular importance. I am also a member of the Dependable Systems Group.

Current extensions of the Internet platform - in particular the Cloud, Web Services Framework and the Semantic Web - are elements of my research. The architecture of services and business processes in service-oriented and cloud computing architectures is an area that joins both directions.

The application of information and software technologies for the development and deployment of learning technology systems, but also other application domains is the main focus.

Specific Research Areas:

Service Architecture Modelling and Evolution: ontology-based architectural description languages to support architecture modelling; graph-based architecture transformation systems; patterns in architecture transformation and evolution; quality and property preservation.
Cloud Brokerage and Interoperability : cloud broker architectures; interoperability solutions for federated clouds; request descriptions and their resolution.
Mediation in Service-based Cloud Computing: data integration for on-demand architectures; ontology-based service mediation for on-demand service systems; multi-tenancy SOA and policy-based governance.
Dynamic SOA/Cloud Models and Monitoring: dynamic context-dependent architectural composition, service models at runtime; context ontology for runtime SOA modelling and composition; constraints monitoring; context and constraints for multi-tenancy SOA and SOA governance.
Business Process and Service Architecture Integration: layered architectural framework for business process and architecture configuration; IT-architecture alignment; graph-based pattern modelling in business processes; pattern identification and discovery techniques.
Ontology-based Information Systems Change and Evolution: ontology evolution; change and evolution patterns; operational support for semantic information systems evolution; change impact analysis.
