Medal for Research Excellence 2000

Leonid S. Dubrovinsky

Born in 1961, Leonid S. Dubrovinsky was student of Crystallography and Crystal Chemistry at the Geological Department of Moscow State University. In 1983, he graduated there with the Master of Science in Geochemistry; he received his doctoral degree in Mineralogy and Crystallography under the supervision of Professor Urusov in 1986. Together with Professor Urusov he is author of the monograph “Computer modeling of crystal structure and properties of minerals” published in 1989. From 1986 to 1996, Leonid S. Dubrovinsky was researcher and senior researcher at the Institute of Geology, Petrology, Mineralogy and Geochemistry of the Academy of Sciences of Russia. Since 1996, he is senior researcher at the Institute of Earth Sciences at Uppsala University, Sweden, and in 1998 he became Dozent in mineralogy, petrology and tectonics.

His experimental and theoretical research covers a broad spectrum from X-ray investigations of crystal structures to calculations of multicomponent phase equilibria. He is author and co-author of two books and about 90 publications; many of them were published in leading international journals.

However, since a number of years his special interest is devoted to ultrahigh pressure research aiming at the determination of phase diagrams and Pressure-Volume-State of Earth materials along the geotherm form the crust to the core. For instance, an X -ray diffraction study of iron and corundum up to 300 GigaPascal was performed which lead to the discovery of new polymorph of iron.

Leonid S. Dubrovinski receives the EMU medal for research excellence for his outstanding theoretical and experimental contributions to the mineral sciences especially by his research on the State of earth materials at ultrahigh pressures and temperatures.

Björn Winkler

Björn Winkler, born in 1962, received his diplom degree in mineralogy with Klaus Langer as supervisor at the Technical University of Berlin in 1988. Then he went to the University of Cambridge and obtained his Ph.D. in 1991 with the thesis “Static and dynamic models of mineral energetics” which was supervised by E. Salje and M.T. Dove. After his time at Cambridge, Björn Winkler spent one and a half year at the Laboratoire Leon-Brillouin, Saclay, in France working on modem methods of neutron scattering. Since 1993 he is at the University of Kiel where he qualified as university lecturer with the thesis “Neutron spectroscopic and theoretical studies on minerals of tri-chlor-germanates” and holds a permanent staff position.

Bjöm Winkler is author and coauthor of more than 40 publications in prestigious international journals. In his crystallographical and mineralogical studies he uses neutron scattering, X-ray diffraction and spectroscopic methods. One of his favourite topics is the study of the dynamics of molecular water in minerals. Special recognition received his work on computational mineralogy. Björn Winkler receives the EMU medal of excellence for his outstanding contributions to the mineral sciences by his detailed studies of crystal structures and by the promotion of computational mineralogy in Europe.
