=====Research Interests=====

  * Theory of spin excitations and magnetization dynamics in transition metal nanostructures.
    * In particular, the influence of spin-orbit coupling on such excitations. 
  * Spin dependent transport in nanostructures.
  * Generation of pure spin current by out of equilibrium magnetization.
  * Spin-charge signals interconversion via spin-Hall and inverse spin-Hall effects.
  * Spin relaxation in the presence of electron-phonon coupling and disorder.
