Works on a range of topics in condensed matter theory, especially in mesoscopic physics and spintronics. Examples include spin filtering and spin splitting due to the spin-orbit interaction, combined with a variety of mechanisms which break time reversal symmetry, decoherence due e.g. to telegraph noise, Josephson junctions with spin-orbit active links, transport via molecular junctions (including full counting of the current distributions and noise), thermoelectricity (e.g. in three-terminal devices), multiferroics, and more.
Research achievements include: Explained spin splitting in chiral molecules, proposed mechanisms to enhance the efficiency of mesoscopic thermoelectric devices, and more.
Future directions continue along all of the above lines.
