My research interest is on the magnetic and electronic properties of iron-bearing materials, particularly nanophase iron oxides and hydroxides with implications to environmental magnetism. Current research is focused on chemical synthesis and characterization of nanophase ferrihydrites, silica coated nanomagnetite for biomedical applications and mechanochemical reaction of metal/metal-oxides with hematite-Fe2O3 as well as MxFe3-xO4, where M is Ni, Zn or Co using ball milling.
