Prof. Dr.-Ing. Wolfgang Lehner is full professor and head of the database technology group at Technische Universität Dresden (TU Dresden), Germany. He received his Master's degree in Computer Science in 1995 from University of Erlangen-Nuremberg. He continued his studies as research assistant at the database system group until 1998, when he earned his Ph.D. degree (Dr.-Ing.) with a dissertation on optimization of aggregate processing in multidimensional database systems. Thereafter (11/1998) he joined the Business Intelligence (BI) group at the IBM Almaden Research Center in San Jose (CA), where he was involved in projects on adding materialized view support and multiple query optimization techniques to the core engine of the IBM DB2/UDB database system. After his return to Germany, he again joined the database system group at University of Erlangen-Nuremberg as senior researcher. Together with his group, he initiated comprehensive research in exploiting database technology to support complex message-based notification systems. From 10/2000 to 2/2002, Wolfgang Lehner was on a temporary assignment at the University of Halle-Wittenberg holding the professorship for database systems. In 7/2001 he finished his habilitation with a thesis on subscription systems and was therefore awarded with the venia legendi. Since 10/2002, Prof. Lehner has been conducting his research, teaching his students, and is involved in multiple industrial projects at the TU Dresden. Wolfgang Lehner was temporarily visiting scientist at Microsoft Research in Redmond (WA), at GfK Nuremberg, at SAP Walldorf, and at SAP Palo Alto. Wolfgang Lehner is a member of the Review Board on Computer Science of DFG (German Research Foundation). Since 2014, Wolfgang Lehner is a member of Academia Europaea (The Academy of Europe). 


Up to now, Wolfgang Lehner has published five books on multidimensional database systems (1999), subscription systems (2001), database technology for data warehouse systems (2003), the XQuery database language (2004), and web-scale data mangagement for the cloud (2013). He is also editor of a large variety of journals, books, and proceedings. Additionally, he published more than 200 reviewed research papers in conference proceedings and international journals. Details can be found at the group’s publication page or at the Publication list at the Databases & Logic Programming bibliography server, Univ.Trier, Germany.

Academic Projects and Industrial Relationship

Wolfgang Lehner conducts are variety of different research projects with his team members ranging from designing data-warehouse infrastructures from a modeling perspective, supporting data-intensive applications and processes in large distributed information systems, adding novel database functionality to relational database engines to support data mining/forecast algorithms, investigating techniques of approximate query processing (e.g. sampling) to speed up execution times over very large data sets, and exploiting the power of main-memory centric database architectures with an emphasis on modern hardware capabilities. Apart from basic and mostly theoretic research questions (supported by Technische Universität Dresden and the German Research Foundation, DFG) Prof. Lehner puts a strong emphasis on practical research work in combination with industrial cooperations, on an international, national, and regional level. Projects are sponsored by BMBF or EU. Wolfgang Lehner also maintains a premium research relationship with the SAP HANA Data-Management Platform group at SAP Walldorf, SAP Palo Alto, SAP Korea, and SAP Waterloo.

General Commitment

As full professor at a German university and member of the Faculty of Computer Science at Technische Universität Dresden, Wolfgang Lehner is committed to Excellency in research and teaching. From a teaching point of view, this commitment implies to offer interesting courses ranging from general and basic methods to topics which are currently discussed within the research community. Moreover, all teaching courses have to be designed to provide a good mix of theory and practical aspects. From a research point of view, this commitment implies actively contributing to and energetically stimulating the work of the associated research assistants to substantially pushing the envelope in the targeted research area. Publication of excellent research results at an international level and the transfer of the existing knowledge and techniques to industrial partners are the primary goals.
