Self-introduction

I am a postdoctoral researcher in Cybermedia Center of Osaka University in Japan. I have interest in statistical physics of driven systems and in their application to spintronics and biophysics. My recent main subject is an application of non-equilibrium statistical physics and thermodynamics to a current induced dynamics of defects (magnetic domain wall, vortex, skyrmion, bloch line), turbulence or chaos in spin systems, diffusion of soft matter and protein structural fluctuation.
