Tenured scientist at Inria (National Institute for Research in Digital Science and Technology), member of the I4S team (Inria – Univ. Gustave Eiffel).
Research interests / field of activity:
I use a combination of physical models, computational methods and lab experiments to develop physical insight into the dynamics and acoustics of complex materials. I aim for a methodological framework to engineer, assess and monitor innovative lightweight structures.
My current research interests are threefold (publications):
-
Wave physics in complex media & applications:
Understanding the physics of elastic wave propagation in periodic, heterogeneous or multi-physical waveguides and its consequences in dynamics and acoustics. Phenomena such as wave conversion, localization and interface diffusion are exploited to develop original wave-based strategies, for damage inspection, material identification or even de-icing techniques.
-
Functional materials for Noise Vibration and Harshness:
Innovative material concepts are developed for noise and vibration control. It includes tailored lightweight periodic or composite structures as well as architectured, 3D printed, enriched or locally resonant metamaterials. A typical objective is to enhance the Sound Transmission Loss of structures subjected to broadband structural or acoustic sources.
-
Multiscale modelling and advanced simulation techniques:
New methodologies are developed, exploiting finite elements, periodic structure theory, model-order reduction, wave-based and modal decompositions. The objective is to build high-resolution and computationally efficient models for structural dynamics and vibro-acoustics. Digital twins, model-based NVH and SHM engineering applications are considered.
Short bio:
I joined Airbus Helicopters in 2012 as a R&D industrial doctorate applicant, after studying fundamental mathematics, physics and engineering. My goal was to develop an in-flight wave-based de-icing solution for composite helicopter rotor blades. In 2015 I received a PhD degree in Structural Dynamics at Ecole Centrale de Lyon.
Between 2015 and 2019, I made several postdoctoral stays at the Tribology and Systems Dynamics Laboratory (LTDS) and the Katholieke Universiteit Leuven (KU Leuven), where I pursued research on multiscale modelling, periodic design and vibration control in collaboration with Profs. Desmet and Ichchou. I was also European Project Manager, invited researcher at the University of Sherbrooke and involved in several academic and industrial collaborations and European projects.
Between 2019 and 2021, I was awarded an Individual Skłodowska-Curie Fellowship, aiming to explore new scattering feature-based damage assessment techniques for lightweight periodic structures, which I held in the Noise and Vibration Research Group at KU Leuven. I was plenary lecturer at the ‘Young Promising Talents’ session at the international MEDYNA 2020 conference and I am the laureate of the 2020 Young Researcher Prize in Science and Engineering awarded by the Lyon Metropolis.
In 2021 I joined Inria as a research scientist (Inria Starting Faculty Position) in the I4S team.
