07/2015-09/2015, third year at the École nationale supérieure de géologie, Nancy. Arriving right after Oleg’s internship, Clémence took over his finite-difference optimal-operator code. She cleaned up the code and wrote an EAGE proceeding with me during the internship. As she is a guitarist, Matthias, Clémence and I gave a few small street concerts in Paris. She became a geophysicist at TotalEnergies.
