> Presentation

Dr. Lemonia Ragia has a diploma degree from the Department of Rural and Surveying Engineering at the Aristotle University of Thessaloniki, Greece. Her doctoral degree was at the Institute of Photogrammetry, University of Bonn, Germany supervised by Prof. W. Förstner. Her doctoral thesis was entitled A data quality model for validating photogrammetric data acquisition funded by the German telecommunications company DeTeMobil GmbH. After completing her doctoral thesis she was a Postdoctoral Fellow at Knowledge Discovery Team, Fraunhofer Institute for Autonomous Intel lnteligent Systems (IAIS now) working on spatial data mining. After that she worked as a senior research scientist at the Information Systems and Database Technology of the Computer Science Department of the Technical University of Aachen, Germany working in the area of spatial data bases and data integration. In 2003 she visited the database group of Phil Bernstein at Microsoft Research, Seattle, USA to work on model management and schema matching. After that she is Maitre Assistant at the University of Geneva, Switzerland working on location based services and 3D modelling of spatial data in the Advanced Systems Group. She was a Visiting Professor at the University of Toronto, Canada working on high performance visualization of spatial information in the Dynamic Graphics Project.
