Scientific interests:
- Applications of X-ray Absorption Spectroscopy (EXAFS, XANES) and micro-XRF in Geosciences using Synchrotron Radiation
- Investigations at in-situ conditions
- Redox relationships and structural environment of heterovalent elements in silicate melts and implications for magmatic processes
- Structural environment of trace-elements in melts
- Determination of redox state with spatial resolution using micro-XANES
- Interactions of solids and magmas with fluids – controls of trace-element partitioning
Projects:
