Biography

I am a PhD student under the supervision of Xavier Claeys and Frédéric Nataf at Inria and at Laboratoire Jacques-Louis Lions (LJLL), working in the joint Inria-LJLL project team Alpines. My thesis is funded by the ANR (French National Research Agency) via the ANR project NonlocalDD.

My research focuses on 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.

Starting next October, I will be a Research Associate in Euan Spence’s team at the University of Bath. I will be part of the EPSRC-funded project At the interface between semiclassical analysis and numerical analysis of wave propagation problems.
