Research interests: physico-chemical interaction processes between coexisting silicate, carbide, sulfide, and/or metal phases
- textural equilibria of iron sulfide liquids at elevated temperature and pressure
- partition behavior of siderophile and chalcophile elements during early history of planets and planetesimals
- fractionation of platinum group elements during mantle melting

physico-chemical interaction processes between coexisting mineral phases, fluids and/or silicate melt phases
- dynamics and kinetics of melt-fluid-rock interactions
- micro- and nano-scale interactions of mineral phases with melts and fluids
- fluid-solid and fluid-melt-solid partition coefficients of fluid-mobile elements
- seawater-rock (MORB) interaction and resulting element partitioning in supercritical hydrothermal systems

physico-chemical interaction processes between pressed-in CO2 with circulating saline fluids and host rock’s mineral and cement phases
- chemical reactions of pressed-in CO2 with circulating saline fluids and mineral and cement phases of the host rock
- alteration processes of cap rock textures due to percolating CO2-enriched brines
- microtextural changes of reservoir rocks due to alteration processes at pressure and temperature conditions of CO2 underground deposits

physico-chemical interaction processes between coexisting mineral phases and fluids (e.g., meteoric water)
- crystal chemistry and thermodynamics of environmentally important natural and synthetic phases containing toxic elements, in particular Se and As

synthetic nanocomposite ceramics – tailored alternative materials
- nano-polycrystalline geomaterial composites with excellent mechanical properties made of economical non-critical materials (SiO2, Al2O3)

differentiation of basaltic melts with the main emphasis on the origin of SiO2-rich residual melts

magma mixing and mingling processes
- combination of field observations with experimentally and theoretically based research (e.g., monitoring real time mixing and mingling by in-situ synchrotron radiographic images)
