Scientific Interests Magnetosphere – Ionosphere – Thermosphere (MIT) coupling Investigate how the solar wind influences planetary atmospheres Solving the gas giant energy crisis Magnetospheric physics Low frequency magnetohydrodynamic (MHD) waves in giant planet magnetospheres Saturn’s peculiar periodicities

Proposed work at ESAC Solving the gas giant energy crisis Why is Jupiter’s atmosphere so hot? Where does the extra heat come from? Solar EUV alone; Strobel and Smith, 1973. Galileo probe; Seiff et al 1998 Caused by redistribution of heat from the interaction with Jupiter’s magnetosphere
