About me

 

I have been involved in research activities since 2004, first focusing on the observation and study of the Southern Ocean, and then increasingly shifting toward the study of the large-scale circulation of the global ocean.

Main Research interests

  • Southern Ocean circulation
  • Instrumented Elephant Seals gathering hydrographic data (MEOP)
  • Ocean modelling (NEMO, MITgcm)
  • Ocean energetics and thermodynamics (TEOS-10)
  • Structure and dynamics of the Antarctic Circumpolar Current
