Research interests

My research interests cover a broad range of topics, including:

1.- Electron and spin dependent transport in carbon based materials, such as magnetic tunnel junctions with buckyballs(C60), and spintronics in graphene, carbon nanotubes and other organics.

2.- Magnetic field dependent transport in nanostructures, such as magnetic oxide nanoconstrictions (Fe3O4, NiOx, LSMO) and gas-stabilised break junctions.

3.- The electron/spin-phonon interaction in hybrid devices (probed by Raman, Brillouin light scattering and other techniques).

4.- Biomagnetism and novel mechanisms of interactions between RF/microwave magnetic fields and proteins.

5.- Exobiology and protein dynamics in conditions simulating those of other planets and/or outer space, including Raman microscopy at low temperatures (down to ~3 K) or under simulated microgravity using magnetic fields.

6.- The magnetic and optical properties of magnetic nanoparticles for device and biological applications.
