Rémi Cornaggia

I obtained in 2016 a PhD in Applied mathematics from the University Paris-Saclay and a PhD in Civil Engineering from the University of Minnesota, thanks to a joint program between those universities, for a thesis prepared in teams POEMS (Applied maths department, ENSTA Paristech) and in the Department of Civil, Environmental and Geo-Engineering of the UoM.

This thesis is entitled Development and use of high-order asymptotic methods to solve inverse scattering problems and was supervised by Marc Bonnet and Bojan B. Guzina.

I then spent two years (2016-2018) as a post-doc researcher in the teams Mathematical modeling for mechanics and Numerical Analysis of IRMAR (University of Rennes-1), thanks to a fellowship granted by the Centre Henri Lebesgue for a research project presented with Loïc Le Marrec, Éric Darrigrand and Fabrice Mahé.

In 2018-2019, I was a postdoctoral researcher at LMA (Laboratoire de mécanique et d'acoustique) in Marseille, thanks to a fellowship granted by the Labex Mécanique et complexité for a research subject proposed by Bruno Lombard and Cédric Bellis.

I am now employed by the company Inovsys as a post-doctoral researcher, and still work part-time at LMA.
