About
Research
I use X-ray diffraction to characterize the structure of materials, especially ferroelectric oxides with a tetragonal tungsten bronze structure. I have experience working with powder diffraction and conventional Rietveld analysis, but also resonant diffraction, diffraction anomalous fine structure (DAFS) og symmetry mode analysis.
My current research interest evolves around the crystallography of modulated structures.
Background
For my PhD I worked on developing hydrothermal synthesis routes for ferroelectric nanomaterials. I utlised in situ X-ray diffraction to study the formation and growth in real-time. Then I moved on to a Postdoc position at ESRF where I used the unique capabilities of the high-resolution powder diffraction beam line ID22 to study the small structural subtelties in Ba2NaNb5O15 and A-site cation order/disorder in SrxBa1-xNb2O6.
