My research interests lie in space plasma phenomena. This includes particle acceleration in the solar wind, interactions between the solar wind and planetary magnetospheres and surfaces, sources and evolution of magnetospheric plasma, wave-particle interactions, and space flight instrumentation. Experience includes comprehensive studies of solar wind-originating plasma injection and subsequent evolution in the magnetospheres of Earth and Saturn, investigations on EMIC wave generation and propagation in the Earth’s outer magnetosphere, particle acceleration in stream interaction regions, as well as space flight instrumentation and calibration.
