About

Ross W. Boulanger is a leading figure in geotechnical earthquake engineering, with a career dedicated to advancing the understanding of soil behavior under seismic loading. His research focuses on the seismic performance of earth dams, embankments, and foundations, with particular emphasis on liquefaction, soil-structure interaction, and the development of performance-based design methodologies. Boulanger has made seminal contributions to the characterization of liquefaction triggering and its effects on civil infrastructure, producing widely used empirical models and design guidelines. His work has been instrumental in shaping modern practice for evaluating and mitigating seismic risks in geotechnical systems. Among his notable achievements, he has been a key investigator at the Center for Geotechnical Modeling at UC Davis, where the NEES geotechnical centrifuge—a 9.1-m radius facility equipped with a servo-hydraulic shaking table—has been used since 1994 to simulate earthquake effects on soil-structure systems. This facility, highlighted in his 2004 paper with 15 citations, underscores his role in advancing experimental capabilities. With thousands of citations across his publications, Boulanger’s impact is profound, earning him recognition as a Distinguished Member of ASCE and a recipient of the Norman Medal.
