CHAUMONT-FRELET Théophile

Théophile Chaumont-Frelet is a junior researcher at Inria, France, affiliated with the Rapsodi project team. He specializes in partial differential equations, numerical analysis, finite element methods, discontinuous Galerkin methods, multiscale methods, high-performance computing, wave propagation, geophysics, electromagnetism, and nanophotonics. His academic journey includes an engineering degree in mathematical engineering and a master’s in fundamental and applied mathematics from INSA Rouen (2012).

• Education:
  • Engineer in Applied Mathematics from INSA Rouen (2012)
  • Master in Fundamental and Applied Mathematics, Rouen (2012)

His research focuses on numerical analysis of time-harmonic and time-dependent wave propagation problems, particularly addressing the pollution effect in high-frequency simulations and developing multiscale strategies for heterogeneous media. Recent work includes a posteriori error estimates for Maxwell's equations, Helmholtz problems, and DG methods.

Key trends in his publications involve wavenumber-explicit stability analysis, polynomial-degree-robust error estimation, and applications to geophysics and electromagnetism. His awards include the C3I label (Certificate of Skills in Intensive Calculation) from GENCI (2017).

• Scientific Awards:
  • C3I label (2017)

He supervises current and former PhD students/postdocs including Sumit Mahajan, Florentin Proust, Zakaria Kassali, Josselin Defrance, and Patrick Vega. His administrative roles include membership in the national INRIA committee for PhD students.
