Research and supervision of PhD students and guest researchers. Responsible for mineralogical laboratories. Administrative tasks as Acting Head of the GEO Department.
A major part of my research deals with the occurrence of low contents of hydrogen in the so-called “Nominally Anhydrous Minerals (NAMs)", such as pyroxenes and garnets. The aim is both to understand the mechanisms of hydrogen incorporation, as well as the role of NAMs in the upper mantle as a water reservoir, or how phenocrysts of these minerals in volcanic settings can be used as a probe of magmatic water contents.
In a collaboration project directed to the hydrous tourmaline minerals, we study how larger hydrogen contents causes ordering effects and affect structural stability. An additional project focuses on structural-chemical studies of spinel-group minerals by X-ray diffraction and spectroscopic methods. Here, we work mainly with synthetic minerals produced by flux-growth methods to obtain crystals with controlled composition in order to study composition-dependent properties.
