Job Opportunities

  • If you'd like to apply for a Marie-Curie Individual Fellowship in our team on the sept 2021 deadline, don't hesitate to contact us well in advance to have plenty of time to build a strong project. We have a very good success rate (100 % on 3 attemtps so far ;-)).

Research topics

  • Physics of erosion processes and sediment transport in mountain rivers.
  • Terrestrial and Airborne Laser Scanning applied to geomorphology
  • Topo-bathymetric airborne lidar for river monitoring
  • Impact of extreme events and on landscape dynamics (floods, earthquakes...)
  • Stochastic geomorphology
  • Biogeomorphological couplings in estuarine dynamics
  • Impact and signature of climate and tectonics in landscapes
  • Experimental and numerical modelling of landscape and channel evolution.
