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.

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 .
