Prof. Dr.-Ing. Wolfgang Lehner (1969) is full professor and head of the 
database technology group at the Dresden University of Technology 
(Technische Universitdt 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 the optimization 
of aggregate processing in multidimensional database systems. Thereafter (11/1998)
he joined IBM Almaden Research Center in San Jose (CA) as a postdoc (DB2, BI Group,
Hamid Pirahesh). Back 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 finally, he finished 
his habilitation with a thesis on subscription systems and was therefore 
awarded with the venia legendi. Since 10/2002, Prof. Lehner is conducting his 
research, teaching his students, and is involved in multiple industrial 
projects at the TU Dresden. In 2004 and 2006, Wolfgang Lehner was also 
visiting scientist at Microsoft Research (SQL-Server group, Paul Larson) in 
Redmond (WA). His current research focusses on 'Data(base) Analytics' ranging 
from theoretical work (sampling, mining uncertain data) to system architectural 
issues (query optimization, realtime processing of data streams).
