Particle acceleration and the dynamics of current flow in the earth’s auroral zone. Related areas include generation of electric and magnetic fields in the magnetosphere, plasma instabilities and turbulence, wave heating of ions, magnetic reconnection, and magnetohydrodynamic waves and turbulence. Both analytic and numeric techniques are used, with present emphasis on development of large scale computer models of auroral phenomena.
