Bio

Eliz-Mari Lourens is an assistant professor in Structural Monitoring and Identification at the Faculty of Civil Engineering and GeoSciences. Apart from her activities in the field of structural health monitoring, she is also responsible for lectures, research projects and MSc thesis work related to offshore wind energy. She is the (co)author of about 40 publications (journals, book chapters, conference papers) related to vibration data analysis for health and load monitoring of civil and offshore structures.

Before joining Delft University, Eliz-Mari completed her PhD at the Structural Mechanics research group of the KU Leuven within the framework of the project 'Generic Methodologies for Inverse Modeling of Dynamic Problems in Civil and Environmental Engineering', where she focused on the identification of dynamic loads from vibration response measurements. Her research is currently focused on linear and nonlinear state/input/parameter estimation, damage detection, optimal sensor placement, system identification, and machine learning, with applications in the fields of wind energy, arctic engineering, and health monitoring of civil infrastructure.

Eliz-Mari additionally holds the position of Assistant Editor for the Journal of Sound and Vibration, and acts as reviewer for numerous international scientific journals.
