Supervisor: Yann Klinger
- Kinematics and seismic behavior of active faults: Distribution of large earthquakes (M ≥ 6.5) in time and space, temporal evolution of deformation rates, from a few years to several 100 ka, creeping faults, coseismic displacements
- Quaternary Geochronology techniques as evolving tools: combining techniques for dating, methodological calibrations, and to understand erosion / transport / deposition / post-deposition processes
- Connate fields: Tectonic plates kinematics, structural geology, river processes, paleo-climatology, paleo-environments, pedology, archeology…
Field experience and laboratory skills
- Geodesy (GPS): Organization of GPS campaigns and data acquisition in the field, GPS data processing using GAMIT/GlobK software, geophysical and tectonic interpretation
- Paleo-seismology: Trench digging, data acquisition and interpretation
- Tectonic geomorphology: Mapping of active faults and Quaternary formations (satellite imagery, Digital Earth Models, and field work), use of sub-surface structural data to interpret surface deformation
- Quaternary Geochronology:
- 10Be cosmogenic dating: sampling, chemical processing of the samples, processing of the AMS data and interpretation of the 10Be concentrations: exposure ages and erosion rates.
- Optically Stimulated Luminescence (OSL): sampling, chemical processing of the coarse- and fine-grain samples, luminescence signal measurements on TL-OSL Riso reader, and age determination. I have worked on both quartz and feldspar minerals.
- Sampling for 14C dating.
