Research Interests

The general thrust of my research is in field of solar wind-magnetosphere interactions in its various forms, using multi-instrument/spacecraft observations together with ground-based measurements. These are studies within NASA's International Solar Terrestrial Physics Program (ISTP). I work particularly with WIND and POLAR data. Aspects of this research include:
  • The interaction of magnetic clouds with the magnetosphere.
  • Strongly geoeffective configurations observed during the Wind era: 1994-to date.
  • Flow in the magnetosheath. Plasma depletion layer structure. Anisotropic magnetosheath.
  • Electromagnetic ion cyclotron waves in the plasma depletion layer.
  • Ionospheric signatures of interaction processes at the dayside. The optical aurora.
  • Magnetosphere-Ionosphere Coupling at midmorning local times and 70 degree-80 degree magnetic latitudes using spacecraft-ground conjunctions.
  • Kelvin-Helmholtz instability at the magnetopause/inner edge of the boundary layer.
  • Reconnection at the magnetopause and in the interplanetary medium.
  • Energetics of the ring current in its dependence on interplanetary parameters.
The above studies are being extended to encompass solar cycle variations and variations across solar cycles.
I also work on the evolution of magnetic clouds and substructures in solar ejecta.
