2000 IAG Young Author Award.


The IAG Young Author Award for 2000 was split between two winners. The Award consists of a certificate and a check of US$ 500, which was handed out during the opening ceremony of the  IAG Scientific Assembly in Budapest.


The IAG best paper award for young scientist for 2000 was given to Christopher Kotsakis and Rüdiger Lehmann


Christopher Kotsakis

Christopher Kotsakis was born in Thessaloniki, Greece in 1970.  After graduating with a Dipl.-Eng. (Honours) from the Department of Rural and Surveying Engineering at the Aristotle University of Thessaloniki, in 1995, he joined the Department of Geomatics Engineering at the University of Calgary and received his Ph.D. degree in 2000.  His doctoral thesis was entitled, ‘Multiresolution Aspects of Linear Approximation Methods in Hilbert Spaces Using Gridded Data’.  From 1999-2001 Christopher was also a sessional instructor in the same department where he carried on full teaching responsibilities for various undergraduate engineering courses, including gravity field in surveying and geodesy, fundamentals of geodesy, geomatics networks and probability and statistics for engineers. Over the past few years, he has received numerous awards for his excellence in teaching. Upon the completion of his Ph.D. Christopher stayed on at the department as a Post-Doctoral Fellow from 2000-2001, where he conducted research work related to gravity field modeling, advanced estimation and approximation methods, non-probabilistic description of spatial fields using wavelets, and the optimal integration of GPS, levelling and geoid data. Other research interests include estimation theory and inverse problems, Hilbert space methods for Physical Geodesy boundary value problems, and multiresolution and wavelet methods for gravity field approximation problems.  He continues to be a regular reviewer for many scientific journals and conference proceedings series as well as being an active associate member of the IAG since 1997.



                      Rüdiger Lehmann


Rüdiger Lehmann was born in Freiberg (Germany) in 1963. He studied Geodesy at the Technical University of Dresden, finishing his thesis of diploma in 1990.

From 1991 to 1999 he did research work in Physical Geodesy at the Geophysical Institute of University of Copenhagen, at the Danish National Survey and Cadastre, at the GeoForschungsZentrum Potsdam, at the University of Karlsruhe and at the Technical University of Freiberg. In 1994 he received a Ph.D. degree in Geodesy from the Technical University of Dresden.

Currently he is a professor of surveying engineering at the Dresden University of Applied Sciences. His scientific interests are mainly in the field of geodetic boundary value problems, where he also chairs the related IAG subcommission 1.3. Other fields of interest are geodetic problems of gravity and geoid and applications of geodesy to surveying engineering.
