Inria - POEMS team

Biography

I am a researcher at Inria in POEMS team. My research focuses on wave propagation problems, Decomposition Domain Methods (DDM) and Boundary Integral Equations (BIE). I am also developing a library for hierarchical matrix techniques called Htool with a parallelized matrix-vector product using MPI. It can be used via FreeFEM for solving BIEs, via PETSc for black-box compression, and directly via C++ or its Python interface.

Previously, I was a postdoctoral researcher at the University of Bath, where I worked with Euan Spence. I did my Ph.D under the supervision of Xavier Claeys and Frédéric Nataf at Laboratoire Jacques-Louis Lions (LJLL) in Sorbonne Université, and I was a member of the joint Inria-LJLL project team Alpines. My thesis was funded by the ANR (French National Research Agency) via the ANR project NonlocalDD.
