Short Biography
Dr. Ing. Lemonia Ragia has a diploma degree (1993) from the Department of Rural and Surveying Engineering at the Aristotle University of Thessaloniki, Greece. Her doctoral degree (2001) was at the Institute of Photogrammetry, University of Bonn, Germany. Her doctoral thesis was entitled, ‘A data quality model for validating photogrammetric data Acquisition’. After completing her doctoral thesis she joined the Fraunhofer Institute for Autonomous Intelligent Systems as a Post-Doctoral Fellow 2001-2003. Since April 2003 she is working as a research scientist at the computer science department of the Technical University of Aachen in the area of Geoinformatics. She worked in several projects in different application areas of image processing, data quality, and spatial data mining.
In 2003 she visited the group of Phil Bernstein at Microsoft Research to work on schema matching for Geo data.
