I am a physicist working in the following fields:
  • Interaction between the Sun and the planets
  • Ionospheric and atmospheric physics of the terrestrial planets
  • Evolution of planetary atmospheres
  • Analysis of the plasma spectrometer data from the Mars Express, MAVEN, Venus Express and BepiColombo missions
  • Energetic charged particle acceleration
  • Science preparation for the JUICE mission to Jupiter
  • Instrumentation: design and development of the PEP/JEI detector for the JUICE spacecraft
  • Planetary space weather
