Research Interests

My main research interest is the complex relationship between the microstructure, the magnetic or other functional properties of a material and the processing conditions. In order to understand the functional properties of a material, microstructural features in the size range pm-mm must be examined and therefore a multi-scale approach utilising various charactersiation techniques is necessary. The extraction of quantitative parameters from these techniques as input for materials modelling on multiple length scales is a critical part of my work.

I carry out aberration-corrected transmission and scanning transmission electron microscopy (TEM and STEM) combined with energy dispersive x-ray spectroscopy (EDX) and electron energy loss spectroscopy (EELS) in order to study interfaces and phase boundaries at the atomic scale in terms of local crystal structure and chemistry.

On a larger length scale, I use techniques in the scanning electron microscope (SEM) such as imaging, EDX and electron backscatter diffraction (EBSD) and x-ray and synchrotron diffraction based techniques in order to examine the properties of groups of grains, rather than individual interfaces. The magnetic domain structure is also of importance and I use magneto-optical Kerr microscopy and magnetic force microscopy (MFM) to study this.

In addition, I am interested in novel data analysis based on computational methods, particularly using the Python language. Thermodynamic phase stability and metastable phase formation also belong to my interests.
