Summary

 

Summary


Research Associate working within the Natural Magnetism Group at Imperial. Main interests include using advanced electron microscopy techniques to study natural magnetic materials. Current research involves the combination of nanometer resolution 3D tomography and micromagnetic modelling to better understand the link between grain morphologies and magnetic properties, ultimately helping to better understand some of the oldest planetary magnetic records.


REsearch interests


  • Fundamental processes in rock magnetism
  • Application of FIB-SEM techniques with focus on 3D nano-tomography
  • Experimental magnetics including high resolution magnetic imaging (Lorentz, electron holography) to study complex nanomagnetic processes.
  • Micromagnetic modelling

Biography
