Rémi Cornaggia

I am now (from 2020) Maître de conférences (assistant professor) at Sorbonne Université, teaching in the UFR d'ingénierie (engineering department) and conducting my research in team MISES of Institut Jean le Rond d'Alembert. I am interested in the modelling and simulation of acoustic and elastic waves, and to the homogenization and optimization of architected materials and composites. I have been working mainly on inverse scattering problems, vibrations of heterogeneous beams, and homogenisation and optimisation of periodic materials to enhance dispersive effects. My favourite mathematical tools are topological derivatives of various cost functionnals or quantities of interest, volumic integral equations to reformulate scattering problems, and the two-scale homogenisation method to address periodic media. For numerics, I mainly use finite elements, boundary elements, and FFT-based methods for numerical homogenisation. _**Short CV (to provide some context to the list of publications):**_ 2020 - present : Maître de conférences (assistant professor), Institut d'Alembert, Sorbonne Université, Paris, France 2019-2020 : postdoctoral researcher, Inovsys and LMA, on the modelling of thermo-viscoleastic composites for fused deposition processes. 2018-2019 : postdoctoral researcher, LMA (Laboratoire de mécanique et d'acoustique), Marseille, France. Fellowship granted by the Labex *Mécanique et complexité* for a research subject proposed by Bruno Lombard and Cédric Bellis, on the homogenization and topological optimization of microstructured media and interfaces. 2016-2018 : postdoctoral researcher, teams *Mathematical modeling for mechanics* and *Numerical Analysis* of IRMAR (University of Rennes-1, France), thanks to a fellowship granted by the *Centre Henri Lebesgue* for a research project with Loïc Le Marrec, Éric Darrigrand and Fabrice Mahé. We worked on enriched finite element methods to simulate the vibrations of heterogeneous beams. 2016 : PhD in Applied mathematics, University Paris-Saclay and PhD in Civil Engineering, University of Minnesota (joint PhD program) Thesis entitled *Development and use of high-order asymptotics to solve inverse scattering problems*, prepared in teams POEMS (Applied maths department, ENSTA Paris) and in the Department of Civil, Environmental and Geo-Engineering of the UoM, and supervised by Marc Bonnet and Bojan B. Guzina.
