• The main research theme of my group is about the dynamic interactions between the Earth’s magnetosphere, ionosphere, and thermosphere, in particular magnetosphere-ionosphere electrodynamic coupling during geomagnetic disturbances (e.g., storm, substorm, and solar wind dynamic pressure variations), formation and evolution of multi-scale ionospheric density structures (e.g., storm-enhanced density, polar cap patch, mid and high latitude troughs, equatorial plasma bubble), as well as their space weather impact.
  • We analyze, interpret and model observations obtained by various ground-based (i.e., coherent and incoherent scatter radars, GNSS receivers, auroral imagers, magnetometers, digisondes) and space-based (auroral imagers, magnetometers, drift meters, energetic precipitating particle detectors) instruments.
