Ph.D. :

High mountain ice : glaciological study and numerical modeling

Under superivision of : Ludovic RAVANEL, Philip DELINE (EDYTEM)

Collaboration :
Institut des Géosciences de l’Environnement (IGE), Grenoble, UMR 5001
Institut des Sciences de la Terre (ISTerre), Grenoble, UMR 5275

Keywords : Mont-Blanc massif, Permafrost, Numerical methods, Bayesian statistics, Ground Penetrating Radar, Glaciology, Python programming, Signal Processing, Markov Chain Monte-Carlo.

Abstract :

As a Ph.D. student at EDYTEM, I study glacier/climate relationships in the Mont-Blanc massif. My work is structured around 3 main axes :

1) Glaciology of steep high mountain ice : Dating and microscopic study of ice cores

2) Modelling changes in thermal, hydrologic and dynamic regimes of North-oriented steep glaciers using numerical methods

3) Reconstructing high mountain cryosphere surface area variations using a specifically developed Bayesian photogrammetric method
