Proposals for thesis
Gli argomenti di tesi proposte vertono sui seguenti argomenti:
1. meccanica delle faglie e dei terremoti (studi sperimentali, teorici e di terreno)
2. attrito, reologia e usura nelle rocce (studi sperimentali, microstrutturali e teorici)
3. studi microstrutturali, mineralogici e geochimici di rocce di faglia
4. rilievi geologico-strutturali di zone di faglia sismogenetiche
5. modellazione numerica di propagazione di rotture sismiche
6. studi sperimentali di sismicità indotta.

Curriculum Vitae
He is Full Professor in Structural Geology at the University of Padua (Italy), Visiting Researcher at the School of Earth and Environmental Sciences at Manchester University (UK) and Associate Researcher at the Istituto Nazionale di Geofisica e Vulcanologia (INGV, Rome). He has 15 years' experience in seismic-related fault processes and published 89 peer-reviewed papers and co-edited three special volumes on this topic. In collaboration with geologists, geophysicists and engineers, he integrated field data from exhumed seismogenic faults with experimental observations to understand the physico-chemical processes active during the seismic cycle. The scientific and technological results of this collaboration include the investigation of several fault weakening processes that may operate during earthquakes, the development and installation of SHIVA, currently the most powerful rotary shear installed worldwide and the installation of a second experimental apparatus at the Dept. of Geosciences in Padua University. His research activities were also supported by two European Research Council Grants (USEMS & NOFEAR, 2008-2019, 4 M€). He received the International Award for Geology from the Accademia dei Lincei (Italy, 2010), the Arne Richter Award of the European Geoscience Union (Vienna, 2008) and he is member of the Academia Europeae (from 2013) and Accademia Galileiana (from 2014).
