11/2013-01/2014, post-master, supervised by Satish Singh and me. Coming from Télécom Paris, Moustapha cleaned up the code for seismic wavefield extrapolation in an acoustic medium. Applying this tool to the Sumatra data, I realised the limits of the methodology, which later led me to develop an extrapolation code using full Green’s functions with Shihao Yuan. Moustapha is now an IT consultant.
