Main research topics: |
| |
- Investigation, characterisation, and refinement of crystal structures: single-crystal and powder X-ray diffraction investigation of minerals, and synthetic inorganic and organic materials also under extreme conditions including synthesis, Rietveld refinements, neutron diffraction, and thermal studies, determination of new minerals
|
| |
- Mineral resources: deposits of ores and industrial minerals (formation, general mineralogy, inclusions)
|
| |
- Applied mineralogy and materials science research: focus on microporous materials such as zeolites, mullite-precursors (crystal chemistry, physical properties, synthesis)
|
| |
- Applied mineralogy and materials science research: focus on gems and gem materials: identification, charcterisation, treatment, imitations
|
| |
- Trace hydrogen and hydrous species in nominally anhydrous minerals (NAMs) and hydrogen bonding in inorganic materials: spectroscopic (mainly IR absorption) studies
|
| |
- Radiation effects in natural minerals, incl. alteration as induced by artificial irradiation (structural, chemical, spectroscopic, and isotopic characterisation and mathematical modelling)
