Kenneth Assogba

I'm a PhD student in the Reactor Studies and Applied Mathematics Department of French Atomic Energy Commission CEA & in the Center of Applied Mathematics CMAP of École Polytechnique under the direction of Grégoire Allaire and the supervision of Lahbib Bourhrara.

I am contributing to the development of an industrial reactor physics platform, namely the Apollo3 solver. My research focused on three aspects of the neutron transport problem

• the simulation of reactor cores and fuel assemblies on 3D unstructured and non-conforming meshes using a combined Discontinuous Galerkin — Spherical Harmonics method
• the numerical analysis (convergence and error estimates) of the scheme
• and parallel neutron transport based on algebraic domain decomposition

I am also Teaching assistant at Paris-Saclay University, giving tutorial on numerical methods and statistics.

My research work is supported by the CEA NUMERICS program, which has received funding from the European Union's Horizon 2020 research and innovation program.
