I am a Lecturer in Ceramics at the Department of Materials. Prior to moving to Imperial I worked at the University of Bayreuth at the Bayerisches Geoinstitut. I obtained her doctorate from the Technical University Berlin for a collaborative effort with the GeoForschungsZentrum Potsdam. I conducted research at the National Centre for Electron Microscopy Berkeley, USA, at the SuperSTEM in Daresbury, UK and at the Carnegie Mellon University of Pittsburgh in the department of Materials Science and Engineering.


My research interests evolve around interfaces and range from their effect on elastic properties, over element transport, to the study of the grain boundary character distribution (GBCD) in polycrystalline samples and microstructure development during deformation at extreme pressures.

Nm-scale processes control not only the formation of nearly everything in our directly accessible world, but also the dynamics of our planet’s interior.

I worked on chemically hazardous fahlore deposits and its potentially perilous weathering products, but also on radioactive decay or element distribution and incorporation in Cu-bearing ore deposits. I have a deep background in the use of various methods for the characterization of micro- and nm-structures in crystalline and amorphous materials, ranging X-ray fluorescence, EMPA, EBSD, FIB and TEM. 

You can find a full list of my publications on Google scholar page.
