PhD Research

I did my PhD in Applied Mathematics at Université Grenoble Alpes from October 2021 to November 2024. The subject of my PhD thesis is about the Optimal Design of Seismic Acquisition Geometries, where we develop a new method to find the best positions of sources and receivers with the objective to enhance the quality of the seismic imaging of a target in the subsurface. The method is based on an illumination condition of a target point in the subsurface (representing a region of interest, for instance oil or gas reservoirs). To that end we use tools from computational geometry, namely Centroidal Voronoi Tessellations. Therefore, the work lies at the intersection of optimization, geophysics, and computational geometry.

The project started in Spring 2021 as a master 2 internship at the LJK, the applied mathematics laboratory in Grenoble, under the supervision of Ludovic Métivier and Édouard Oudet. In October 2021, the project was extended as PhD thesis as part of the Seiscope consortium, with the addition of Romain Brossier as co-director. The project is a joint project between LJK and ISTerre, respectively the labs of applied mathematics and earth sciences in Grenoble. During the last year of the PhD, the project benefited greatly from a collaboration with ACTeQ, a US-based company specializing in the design of seismic survey acquisitions.

After the PhD defense

I defended my thesis on the 6th of November 2024.
