[here is how to pronounce my first name]
I’m the PI of OROG3NY and an SNF-professor at the University of Lausanne.
Research interests
I am interested in the geodynamics of the continental lithosphere: structure, deformation and associated physical processes. My principal tools of investigation are geophysical imaging (seismology, gravimetry) and numerical modelling (themo-mechanical, petrological).
In frame of OROG3NY I currently work on:
- 3D structural mapping with converted waves (Ph.D. Leonardo Colavitti)
- Metamorphism as seen by geophysics (post-doc Kristel Chanard, post-doc Celso Alvizuri)
- Ivrea geophysical body (Ph. D. Matteo Scarponi)
- Seismo-at-school in Nepal (Ph. D. Shiba Subedi)
- AlpArray – a broadband-seismology-array and geodynamics project
- EASI – Eastern-Alpine Seismic Investigation
- GANSSER – Geodynamics ANd Seismic Structure of the Eastern-Himalaya Region (i.e. Bhutan)
Previously I have mostly worked on orogeny, deformation and phase changes (see Publications for more details):
- the Himalaya-Tibet region (crustal and lithospheric structures [Hi-CLIMB project], rheology of the India plate, eclogitization of the lower crust);
- the Alpine-Carpathian-Pannonian region (crustal thickness, mantle transition zone topography and history [CBP project]);
- a numerical approach that does conserve mass during metamorphic phase changes in thermo-mechanical models;
- columnar jointing in igneous rocks (size, composition).
