Pierre Marchand

Research Associate in applied mathematics

University of Bath

I am a postdoctoral researcher at the University of Bath, where I am working with Euan Spence. I am part of the EPSRC-funded project At the interface between semiclassical analysis and numerical analysis of wave propagation problems.

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 is used by FreeFEM and available via C++ or Python.

Previously, 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.
