Daniele Martinelli is Assistant Professor at Department of Environment, Land and Infrastructure Engineering at the Politecnico di Torino. He’s an expert in numerical modelling and in rock masses characterization for applications both open pit and underground. His teaching activity includes Mining Plants, MSc in Petroleum & Mining Engineering – path Mining, Politecnico di Torino; Tunnelling, MSc in Environmental Engineering; Master course in Tunnelling and Tunnel Boring Machines. Main topics of research: Conventional and mechanized excavation, rock mass conditioning for EPB applications, especially regarding the geotechnical characterization of the conditioned material, Tunnelling and Tunnel Boring Machines; he spent a period at Aalto University in Espoo, Helsinki, improving his knowledge on Scandinavian rock masses. He has been working also as a project engineer at Rockplan, located in Helsinki, Finland, since 2010. Carmine Todaro is Post-doctoral research fellow at Politecnico di Torino University (Environment, Land and Infrastructures Department – DIATI). Teaching collaboration: Excavation Engineering and Mining Plants, MSc in Petroleum & Mining Engineering – path Mining, Politecnico di Torino; Tunnelling, MSc in in Petroleum & Mining Engineering, Environmental Engineering, Civil Engineering. Main topics of research: Conventional and mechanized excavation, EPB tunnelling and soil conditioning, wear, two-components grout backfilling, soil and rock improvements, surface and underground mining.
