I am currently working as a postdoctoral researcher at Nanostructures and Fucntional Materials (NAFUMA), Department of Chemistry, University of Oslo. Topics include,
- Low-temperature magnetic, transport and thermodynamic characterization of Ruddlesden-Popper phases of nickelates and cobaltates
- MnA's intermetallics doped with Cr for possible application as a barocaloric material for solid state refrigeration
- Studying metal-into-metal inter-diffusion in model systems for making custom bimetallic alloy model catalysts
Additionally, I support numerous Ph.D., master and undergraduate students on physical property measurements of functional oxide and intermetallic materials.
