Signal and image radar processing
  • SAR processing, SAR interferometry, Differential SAR Interferometry and Geocoding, and Land Application (ROIPAC, GAMMA,PolSARpro, EFIDIR-Tools).
  • Simulation of SAR raw data.
  • Multivariate statistical analysis.
Qualitative and quantitative remote sensing of glacier and permafrost
  • Monitoring Alpine glacier activity (velocity) by image radar processing, by amplitude correlation and by interferometry
  • Validation with in-situ measurements (GPS and corner reflector)
  • Detection of permafrost by image radar processing.
Quantitative remote sensing of snow and ice core dating
  • Assimilation of satellite radar data to constrain the snow model SURFEX / crocus
  • Studies of snow in Alpine regions using a Ground penetrating Radar.
  • Ice-core dating by time-frequency analysis.

Imagery of micro-structures of firn snow and ice
I have developed image processing based on Image Processing Software ( to measure snow grains size, analyzing micro-structure of firn and ice for the purpose of obtaining descriptors of these objects. These parameters were implemented in 3 physical models, a first model of firn densification, a second of pore closure and a third of gas diffusion. They have also been used to improve the laws of grain growth in ice.

Creating the electronic activity
Design and construction (inventor of the tetrahedral structure) of a correlative ultrasonic anemometer (patented).
I've developed a gas exploder for triggering avalanches. I was awarded the 2nd prize for collaboration between laboratory and company, delivered by the Banque Populaire de la Région Dauphinoise.
Realization of a system for measuring physical parameters in snow avalanches.
Measurement of the mass balance of Sarenne glacier (1st series in Europe, 3rd in the world).
