Dr Milen Gateshki is a researcher with the 'Mineralogy at high temperatures and high pressures' project.

His expertise includes X-ray and neutron diffraction, Rietveld refinement and pair distribution function (PDF) analysis, structural studies of nanocrystalline and highly disordered materials, phase transitions, crystallographic symmetry, microstructure analysis, structure modeling, sample preparation and thermal properties.

Milen received his M.S. degree in Solid State Physics from Sofia University (1995) with a thesis on thermal properties of ternary chalcogenide glasses. His PhD in Materials Science and Technology (2003) is from the Department of Applied Physics of the University of the Basque Country - home of the Bilbao Crystallographic Server. Milen's thesis was dedicated to the experimental and theoretical study of the structural phase transitions occurring in a number of double perovskite oxides. After finishing his PhD he joined the Department of Physics of Central Michigan University as a postdoctoral associate (2004-2007). During this period his research was dedicated to structural studies of nanocrystalline materials with applications in electrochemical power sources, catalysts, functional ceramics, etc.

Qualifications and achievements:

• 2003 PhD in Materials Science and technology from the University of the Basque Country, Spain
• 1995 M.S. in Solid State Physics from Sofia University, Bulgaria.
