Research Interests

I am interested in the application of synchrotron techniques to solve materials science problems, for example using x-ray magnetic circular dichroism to determine local magnetic structure, or microtomography to study strain and loading in alloys. I play a small role in a number of projects, including development of exchange spring magnets, hydrogen storage and bio-inorganic hybrid nanomaterials.

My research background is primarily in thin-film magnetism, with an emphasis on ferromagnetic resonance studies of coupled magnetodynamics of spin valves and magnetic tunnel junctions. I have also worked on micromagnetic simulations, magnetically doped topological insulators and skyrmion materials.
