DESCRIPTION:Shear failure of ice during glacier frontal calving events sha
 res many characteristics of rock-slope failures (RSFs) in high mountain ar
 eas\; Nevertheless\, the investigation of gravity-driven instabilities tha
 t shape rock cliffs and glacier fronts have been dissociated research topi
 cs so far.\n\nThe dynamic processes shaping the termini of glacier fronts 
 - and thus directly a major contribution to sea level rise - have attracte
 d the attention of the scientific community. Although recent research has 
 shed light on the dynamics of tidewater glaciers\, a full understanding of
  the calving phenomena is still elusive. This epistemic uncertainty may be
  related not only to the highly non-linear dynamics of the calving phenome
 na\, but also to the 2D nature and the limited spatial and temporal resolu
 tion of the techniques typically used for investigating the rapidly evolvi
 ng glacier front.\n\nThrough my two year Marie-Curie H2020 project\, I am 
 progressively adapting my previous research interests (4D investigation of
  RSF using Terrestrial LiDAR and Structure-from-Motion photogrammetry) to 
 the investigation of glacier front dynamics\, aiming to gain understanding
  of the processes leading to discrete calving events\, to adapt landslide 
 modelling techniques for investigating glacier response to external forces
  and to explore the apparent randomness of calving events. Working in the 
 reverse direction\, this research project will allow me to analyse a pleth
 ora of recorded calving events in order to shed light on natural slope evo
 lution.\n
