Professor of Physics

Research:

Space plasma theory and simulation. Activities address the linear and nonlinear dynamics of macroscopic current carrying plasma systems with applications in the fields of solar wind-magnetosphere interaction, magnetotail dynamics, and the formation and evolution of discrete auroral structures. Current work addresses the three-dimensional evolution of the plasma and the magnetic flux transport at the magnetospheric boundary, the magnetosphere-ionosphere coupling, and the formation of current filaments and thin discrete auroral arc structures.

Research results and overviews are presented in the pages listed on the right. Magnetic reconnection and Kelvin Helmholtz modes are central processes at the magnetospheric boundary and couple the magnetosphere to the solar wind. Magnetotail dynamics plays a major role for magnetic substorms and the associated auroral activity. Processes associated with the interaction between the magnetosphere and the ionosphere (upper atmosphere) are discussed in magnetosphere-ionosphere coupling.
