Personal profile
Associate professor in applied mathematics and numerical analysis at the department of applied mathematics at ENSTA, he conducted research for the study and efficient numerical resolution of partial differential equations (PDE) from mathematical physics. Its scientific activity covers high-performance computing, the development of C++ software oriented towards scientific computation and at the same time more analytical mathematical tools related to potential theory, domain decomposition and asymptotic modeling.
Research interests
His research activities focus on modeling and numerical analysis of linear wave propagation phenomena in the context of electromagnetism and acoustics in the frequency domain. His main areas of interest are:
domain decomposition,
finite element methods,
scientific computing,
multiscale problems,
singularities in elliptic problems.
