Frank Leymann is a full professor of computer science and director of the Institute of Architecture of Application Systems at the University of Stuttgart, Germany. His research interests include service oriented computing and middleware, workflow- and business process management, Cloud Computing, transaction processing, integration technology, and architecture patterns. Before accepting his professor position he worked for two decades for IBM Software Group building database and middleware products: He built tools supporting conceptual and physical database design for DB2; built performance prediction and monitoring tools for an object database system; was co-architect of a repository system; built both, a universal relation system as well as a complex object database system on top of DB2; and was co-architect of the MQSeries family. In parallel to that, Frank worked continuously since the late eighties on workflow technology and became the father of IBM's workflow product set. As an IBM Distinguished Engineer and elected member of the IBM Academy of Technology he contributed to the architecture and strategy of IBM's entire middleware stack as well as IBM's On Demand Computing strategy. From 2000 on, Frank worked as co-architect of the Web Service stack. He is co-author of many Web Service specifications, including WSFL, WS-Addressing, WS-Metadata Exchange, WS-Business Agreement, the WS-Resource Framework set of specifications, WS-HumanTask and BPEL4People; together with Satish Thatte, he was the driving force behind BPEL4WS. Also, he is co-author of BPMN 2.0. Currently, Frank works on the following third-party funded research projects: For the DFG Excellence Cluster SimTech his group contributes a service-oriented environment for modeling and executing multi-scale simulations. In the DFG Excellence Graduate School GSaME work is done on a service-based environment for adaptive business processes in manufacturing environments. The focus of his work in the Nexus DFG Center of Excellence is in the area of context-aware business processes. Within the EU FP7 project ALLOW the focus of research is on enabling the adaptability of flows as basis for building applications in pervasive environments. New mechanisms for composing SOA-based applications and their embedding into corresponding software engineering methods are subject of the EU FP7 project S-Cube . The development of variable Cloud services and their support by an appropriate PaaS platform is investigated in the EU FP7 project 4CaaSt . Similarly, Frank is active in projects that are directly funded by industry. Topics worked on in these projects are from the area of service- and process-oriented architectures as well as cloud computing.
