I am interested in the application of synchrotron techniques to solve materials science problems such as using x-ray magnetic circular dichroism to determine local magnetic structure or absorption spectroscopy (including microscopy) to track changes in chemical environment. Much of my work at LLNL focuses on energy and resource security, with a particular focus on the development of new functional materials and additive manufacturing methods to fabricate them. This has included extensive work with the Critical Materials Institute, and several Technology Commercialization Fund projects. I am also involved with characterisation of thin films for NIF applications, and the hydrogen storage collaboration HyMARC.
My early 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.
