Research Description

Dr. Cabas's research interests include the assessment of seismic hazards, performance-based design in geotechnical engineering, the prediction of the response of soils and foundation systems to seismic loading and dynamic soil-foundation-structure interaction. Her research focuses particularly on the advancement of the current understanding of the impact that local soil conditions have on ground motions, improving the assessment of site-specific seismic hazards, and elucidating the correlation between ground motion parameters and structural response and damage.
