Stefano Marelli
Research
Stefano Marelli received his MSc in Physics from the University of Milano Bicocca in 2006 with a thesis on fast Monte-Carlo simulation of stochastic processes in particle accelerators. His research interests evolved into the field of deterministic inverse theory and its applications during his PhD (2007-2011) in the Applied and Environmental Geophysics group at ETH Zurich. Stefano's doctoral research focused on quantifying the advantages and limitations of seismic full-waveform tomography as a tool for the non-intrusive monitoring of radioactive-waste disposal sites. In particular, he examined the requirements that full-waveform tomography imposes on data quality and forward model accuracy in the presence of high-contrast engineered barriers. Stefano also worked on the laboratory characterization of the elastic properties of bentonite clay and the geophysical interpretation of seismic sections collected from underground rock laboratories in Switzerland. He is currently working as a Postdoctoral Fellow with James Irving in the UNIL Institute of Geophysics, where his research focus is uncertainty analysis in the geophysical inversion of seismic data.
