Othmar Müntener is a Professor of Petrology at the University of Lausanne (Switzerland). He received his PhD (1997) from ETH Zürich. He joined the faculty of Earth and Environmental Sciences in Lausanne in 2006, after research stays at MIT, WHOI, Neuchâtel and Bern. He is a petrologist by training combining field studies, geochemistry, and experimental petrology. He is interested in magmatic aspects of geological processes, from melt production in the mantle to emplacement in the crust. He conducts field work in the Alps, Patagonia and the Himalayas, with a focus on subduction-related magmatic arcs and the evolution of continental crust and ocean-continent transitions. His current interest is in timescales of felsic plutonic systems.

Alberto Zanetti is Research Director of the National Research Council at the Pavia branch of the Institute of Geosciences and Earth Resources. He received his research doctorate in 1994 at the University of Pavia (Italy), and has always carried out research and analytical development at the geochemical microanalysis laboratories of the CNR of Pavia, holding both CNR and university researcher positions. His research is mainly focused on the geochemical and petrological characterization of the production and migration processes of mantle melts, with particular focus on their emplacement at both mantle and crustal levels. These studies are aimed at understanding elementary and isotopic cycles on a geological scale. The research activity has seen the Ivrea-Verbano zone as a privileged area of research since the early 90s. However, research has been carried out to define the processes of mantle evolution and the interplay with the crust in practically every terrestrial geodynamic environment.
