Presentation

I am an experimental geoscientist performing experiments at high temperatures and high pressures with the aim of understanding the evolution of a magma from its source inside the Earth to its final eruption at Earth’s surface. I am particularly interested in planetary evolution and in the study of pre- and syneruptive conditions of active magmatic systems. I am also interested in the application of micro-analytical techniques for the characterization of natural and synthetic materials.

Research topics

  • Influence of redox conditions on the behavior of the Highly Siderophile Elements (HSE) at mantle conditions
  • Mineral/melt partitioning of heterovalent elements as proxies for the oxidation state of magmas
  • Noble gas partitioning between metals and silicate liquids
  • Noble gas solubility in silicate melts at high pressures
  • Halogen incorporation in mantle minerals and their partitioning with aqueous fluids
  • Zoning and diffusion of elements in olivine and melt inclusions to constrain the timescales of syneruptive processes
  • Partitioning of radioactive elements between minerals and melts to recalculate minerals’ residence times
  • REE and halogen in apatite
  • Phase equilibria in magmatic systems
  • Application of geo-hygrometers, geo-thermometers, and geo-barometers to constrain the pre-eruptive conditions

Funded projects

  • 01/2018-12/2020 - GACR (Grant Agency Czech Republic)  Standard Project number 18-01982S: "Experimental determination of the effect of oxygen fugacity on mineral/melt partitioning for the Highly Siderophile Elements at mantle conditions" (132000 EUR).

This innovative project aims, for the first time, to define the role of the oxygen fugacity on the partitioning behavior of the Highly Siderophile Elements (HSE), how they are incorporated in mantle minerals, during mantle melting and crystal-liquid fractionation, and how their bulk partition coefficients change with changing redox conditions. The redox state has a critical effect on the partitioning behavior of the highly siderophile elements during mantle melting. This has had long-term effects on planetary differentiation not only for the Earth, but also for the extraterrestrial bodies. This study will improve both the knowledge of the geochemical behavior of these elements during mantle melting and magma genesis, that the knowledge of differentiation processes in extraterrestrial systems, where the redox conditions are more reduced than those of the Earth, such as the Moon.​
