About Me Publications

Luis Angel Dalguer is a seismologist and structural engineer. He received his first PhD in structural engineering from Federal University of Rio Grande do Sul (UFRGS) and a second PhD in Geophysics (Seismology) from Kyoto University in 2002. In 2018 he opened his own consulting company “3Q-Lab GmbH” providing professional service on seismology and earthquake engineering related problems. He is advisor to the International Atomic Energy Agency (IAEA) on issues related to seismic hazard for nuclear installations. Previously, he was working for the nuclear industry in Swissnuclear as seismic hazard and structural analysis specialist; He also served in research positions at the Swiss seismological service (SED), ETH-Zurich; at San Diego State University, at University of Tokyo, at University of Kyoto. His main research is on physics-based earthquake rupture for near-source ground motion modeling and their engineering applications. His interest includes seismic hazard assessment (probabilistic and deterministic), near-source ground motion evaluation, ground motion prediction equations, site effects, ground motion selection for engineering application, earthquake-resistant structural analysis and design, fragility curves development, risk mitigation.
