Hugo Larnier

PhD student in Geophysics (January 2014 - expected defense February 2017).

Title : Intégration de sondage magnétotelluriques et des données magnétiques d'observatoires: Acquisition, traitements, imagerie.

Research interest:

  • Detection and characterisation of geomagnetic sources using continuous wavelet transform (lightning-based sources, geomagnetic pulsations) in magnetotelluric time series.
  • Magnetotelluric data processing taking into account geomagnetic source information.
  • MT soundings interpretation using tensor decomposition and modeling.

Teaching:

  • 2015-2016: Electromagnetism (44H), Geomagnetism (20H).
  • 2014-2015: Field practice in magnetotellurics and gravimetry (30H), Electromagnetism (44H), Geomagnetism (24H).
