Dr. Alexandru Marin

Senior scientist
Alexandru’s research focuses on soil dynamics and earthquake engineering. Some of the subjects he deals with are soil-structure interaction, seismic engineering of pile foundations, coupled seismogenic geohazards in alpine regions, and design and analysis of slopes under seismic action.

The research subject of Max’s doctoral studies is the soil-structure interaction during seismic shaking with focus on a novel design concept, which is termed rocking isolation. The aim of his studies is to develop and assess simplified analysis methods that can compete rigorous 3D finite element analyses of the entire soil-foundation-structure system. Furthermore, in the framework of an SNF project, he works on the statistical characterization of the rocking motion of uplifting structures, which is a strongly nonlinear, not to say chaotic, problem, where deterministic methods fail. Besides his research activities his professional passion and strong point lies in teaching duties, where he could contribute to various courses of the chair or help supervising bachelor and master students with their thesis.
