My research interests lie in nanostructured Magnetic Materials: their fabrication using advanced lithographic tools (e.g. FIB, EBL, ENSL), characterisation with soft x-ray scattering/imaging techniques and study of fundamental properties for potential technological applications. Current research projects include: development of the time-resolved soft x-ray holographic imaging of magnetic thin film structures; development of self-propelled ferromagnetic micro-swimmers for biomedical applications; development and application of micromagnetic FDTD-LLG simulation code for studies of magnetic metamaterials.
