Chatzi obtained her diploma and master's degree MSc in Civil Engineering with honors from the Department of Civil Engineering at the National Technical University of Athens (NTUA). In 2010 she obtained her PhD Degree with distinction from the Department of Civil Engineering & Engineering Mechanics at Columbia University.
In 2010 Chatzi was hired as the youngest assistant professor at ETH Zurich. She was promoted to an Associate Professor in 2017 [2] [3] and a Full Professor in 2024. [4] Chatzi works in the domains of Scientific and Physics-Enhanced Machine Learning, building data-driven decision-support tools for structures, infrastructures and engineered systems at-large. Her research follows a hybrid modeling approach, coupling physics-based simulation tools with data stemming from monitoring observations [5] [6] [7] [8] for supporting operators and engineers in the management of their assets. [9] She is an expert in the field of Structural Health Monitoring, with applications extending across a range of systems including civil, mechanical and aerospace structures and components. She has delivered a number of works on the state/parameter [10] [11] [12] state/input [13] [14] and state/input/parameter identification of dynamical systems, [15] relying on novel Bayesian filtering formulations. [16] [17] On the hybrid modeling front, Chatzi's work involves a set of approaches for reducing physics-based simulations, drawing from structural mechanics of complex phenomena (plasticity/nonlinear dynamics/fracture), so that these may be fused with data - possibly on the fly, as data is attained. [18] [19] This includes work on computational hysteretic multiscale schemes, [20] [21] [22] schemes for increasing accuracy and stability in fracture simulations, [23] [24] [25] [26] substructuring schemes [27] [28] as well as Model Order Reduction schemes with parametric dependencies. [29] Chatzi has delivered an array of works on efficient dynamic system metamodels that incorporate uncertainties by employing stochastic and machine learning schemes for the purpose of virtualization/digital twinning, [30] [31] online monitoring and control.
Chatzi further serves as an editor for international journals in the domains of Dynamics and Structural Health Monitoring, including the Journal of Sound and Vibration, Structure & Infrastructure Engineering, the Journal of Structural Engineering, Mechanical Systems and Signal Processing, the Journal of Engineering Mechanics, as well as the Sections on Structural Sensing and Computational Methods in Structural Engineering of Frontiers in Built Environment. From 2016-2021, she served as coordinator of the joint ETH Zürich & University of Zurich PhD Programme in Computational Science. Her work on use of monitoring toward self-aware infrastructures has been honored with the Walter L. Huber Civil Engineering research Prize, awarded by the American Society of Civil Engineering. She is further recipient of the 2020 EASD Junior Research Prize in the area of Computational Structural Dynamics, awarded by the European Association of Structural Dynamics (EASD), the 2023 J.M. Ko Award for excellence in Structural Engineering, and the recipient of the 2024 SHM Person of the Year award, selected by the editors of Structural Health Monitoring: An International Journal.
Topology optimization is a mathematical method that optimizes material layout within a given design space, for a given set of loads, boundary conditions and constraints with the goal of maximizing the performance of the system. Topology optimization is different from shape optimization and sizing optimization in the sense that the design can attain any shape within the design space, instead of dealing with predefined configurations.
Applied mechanics is the branch of science concerned with the motion of any substance that can be experienced or perceived by humans without the help of instruments. In short, when mechanics concepts surpass being theoretical and are applied and executed, general mechanics becomes applied mechanics. It is this stark difference that makes applied mechanics an essential understanding for practical everyday life. It has numerous applications in a wide variety of fields and disciplines, including but not limited to structural engineering, astronomy, oceanography, meteorology, hydraulics, mechanical engineering, aerospace engineering, nanotechnology, structural design, earthquake engineering, fluid dynamics, planetary sciences, and other life sciences. Connecting research between numerous disciplines, applied mechanics plays an important role in both science and engineering.
Micromechanics is the analysis of composite or heterogeneous materials on the level of the individual constituents that constitute them and their interactions.
Fluid–structure interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow. Fluid–structure interactions can be stable or oscillatory. In oscillatory interactions, the strain induced in the solid structure causes it to move such that the source of strain is reduced, and the structure returns to its former state only for the process to repeat.
Johann Hadji Argyris FRS was a Greek pioneer of computer applications in science and engineering, among the creators of the finite element method (FEM), and later Professor at the University of Stuttgart and Director of the Institute of Structural Mechanics and Dynamics in Aerospace Engineering.
Jean-Baptiste Charles Joseph Bélanger was a French applied mathematician who worked in the areas of hydraulics and hydrodynamics. He was a professor at the École Centrale des Arts et Manufactures, École Polytechnique and École des Ponts et Chaussées in France. In hydraulic engineering, he is often credited improperly for the application of the momentum principle to a hydraulic jump in a rectangular open channel in 1828. His true contribution in 1828 was the development of the backwater equation for gradually varied flows in open channels and the application of the momentum principle to the hydraulic jump flow in 1838.
The Hilbert–Huang transform (HHT) is a way to decompose a signal into so-called intrinsic mode functions (IMF) along with a trend, and obtain instantaneous frequency data. It is designed to work well for data that is nonstationary and nonlinear. In contrast to other common transforms like the Fourier transform, the HHT is an algorithm that can be applied to a data set, rather than a theoretical tool.
In contact mechanics, the term unilateral contact, also called unilateral constraint, denotes a mechanical constraint which prevents penetration between two rigid/flexible bodies. Constraints of this kind are omnipresent in non-smooth multibody dynamics applications, such as granular flows, legged robot, vehicle dynamics, particle damping, imperfect joints, or rocket landings. In these applications, the unilateral constraints result in impacts happening, therefore requiring suitable methods to deal with such constraints.

Bayesian operational modal analysis (BAYOMA) adopts a Bayesian system identification approach for operational modal analysis (OMA). Operational modal analysis aims at identifying the modal properties (natural frequencies, damping ratios, mode shapes, etc.) of a constructed structure using only its (output) vibration response (e.g., velocity, acceleration) measured under operating conditions. The (input) excitations to the structure are not measured but are assumed to be 'ambient' ('broadband random'). In a Bayesian context, the set of modal parameters are viewed as uncertain parameters or random variables whose probability distribution is updated from the prior distribution (before data) to the posterior distribution (after data). The peak(s) of the posterior distribution represents the most probable value(s) (MPV) suggested by the data, while the spread of the distribution around the MPV reflects the remaining uncertainty of the parameters.
