Direct and Inverse Problems related to wave propagation phenomena
I am essentially interested in the numerical simulation of the propagation of waves and I contribute in particular to the construction of new absorbing conditions. I work on time-dependent and stationary equations and I mainly focus on systems which are approximated by finite-element methods. I have active collaborations with the oil company TOTAL for the development of software packages for the seismic imaging in the framework of DIP partnership that I created in 2009 with Henri Calandra (Total).
