I am a Professor of Space Physics in the Department of Meteorology and a member of the Space and Atmospheric Electricity Group (SPATE). I am currently an associate editor for Solar Physics. My primary research interests are:

  • The heliospheric magnetic field
  • Large-scale solar wind structure
  • Empirical and numerical space-weather forecasting
  • Forecast validation methods
  • Reconstructions of long-term solar variability
