Marcos Arroyo is a Civil Engineer specialized in geotechnics. He obtained a PhD from Bristol University (UK), with a thesis on the interpretation of laboratory seismic tests. In 2005 he joined the Department of Geotechnical Engineering and Geosciences at UPC, where he is now Associate Professor and is currently responsible for courses on “Geotechnical design”, “Offshore foundations” and “Marine geodynamics”. He has initiated a variety of research projects there that have attracted more than 4 M€ of public and private funding. His research is problem-driven and relies on different numerical (DEM, FEM, PFEM) and experimental (laboratory & in situ testing) techniques to address questions of geotechnical interest. The outcomes of this research are regularly published in peer-reviewed scientific conferences and journals (see https://www.researchgate.net/profile/Marcos-Arroyo-2). Marcos Arroyo worked for 8 years in geotechnical design offices and acts regularly as consultant in a variety of engineering projects, related to foundations, ground improvement, mineral residues, etc. He is active in several normative committees, notably ISO-TC182 Geotechnical testing and CENTC250- Eurocodes, where he has been part of the drafting teams for the renewed Eurocodes EC7.1 Geotechnical design. General rules and EC7.2. Geotechnical design. Ground properties.
In November 2019 a team led by Marcos Arroyo was designated by the Public Prosecutor Office of Brazil (MPF) to perform numerical modelling of the Brumadinho tailings dam so as to clarify the proximate causes of that abrupt failure. The resulting report, which was made public by the MPF in October 2021 (https://tinyurl.com/cs3tdxd9), will form the basis of the presentation.
