Short presentation
I am interested in Earth structure and what it can tell us about processes such as tectonics and volcanism, but also on a smaller scale where it can provide valuable information on various reservoirs. I work with seismic-wave propagation and the distribution of elastic and anelastic properties inside Earth (tomography) as well as detailed location of their sources (earthquakes and tremor) with some emphasis on uncertainty estimation.
