Research Profile

 

I am interested in the formation and cycling of carbon, sulfur and halogens in the sublithospheric mantle and how they interact with the silicate mantle and contribute to mantle heterogeneities. My research focuses on how bulk rock compositions and redox conditions affect the mobility and partitioning of these elements and how the residual silicates are modified by the interaction with the metasomatic agents.

My research is complemented by looking at the diffusive behavior of elements in mantle phases to figure out how efficient heterogeneities are compensated by diffusion processes and how diffusion-recrystallization processes modify the composition of rock-forming minerals.

To accomplish these goals, I use mainly chemical data obtained from high-pressure and high-temperature experiments.

Lastly, I am keen on improving experimental techniques to enhance the reproducibility of experiments and to open up new possibilities to answer pending questions in earth sciences.


Current Projects

 

For the following current projects, I received third-party funding:

  • DFG project BE 6053/1-1 - Diamond formation in Earth's mantle: Role of C-O-H fluid composition and host rock lithology (until 2023)
  • DFG project BE 6053/2-1 - Chemical and physical properties of magmatic sulfides and sulfide liquids at conditions of Earth’s deep upper mantle (until 2023)

Collaborations:

 

  • Dr. Jasper Berndt (WWU Münster)
  • Dr. Katharina Marquardt (Imperial College London)
  • Catherine McCammon, Ph.D. (University of Bayreuth)
  • Robert Myhill, Ph.D. (University of Bristol)
