My primary interest is in studying the physics of geomagnetic storm and auroral substorm processes. However, I am also interested in studying and understanding the end-to-end system of solar-heliosphere-magnetosphere-ionosphere coupling and dynamics, to include evaluation of new computer modeling techniques for forecasting purposes. Some of the top research questions I would like to address are:

  • What physical processes contribute to the magnetic field fluctuations that define a geomagnetic storm?
  • What role do field-aligned currents, and the associated inter-connection of magnetospheric current systems, play in the geomagnetic storm process?
  • What are the most important measurements necessary to support real-time evaluation and forecasting of space weather conditions?
  • What are the operationally significant thresholds of space weather conditions?
  • What is the effect of space weather disturbances on aviation operations?

I am also currently studying the history of space weather, especially how the understanding of space weather evolved throug the 18th and 19th centuries.
