Christophe Barnes - UCP

Dr Yassine Abdelfettah has more than 10 years of experience in geophysics applied to geothermal projects. He is experienced in geophysical data acquisition, data processing, numerical modelling and inversion, home software development, data interpretation for the gravity, seismic and electromagnetic methods. He is experienced in combing seismic and non-seismic data for both academic and industrial projects. He got his petroleum engineer in 2003 and his PhD thesis in 2009. In 2017, he created his own geophysical company expert in magnetotelluric and gravity. Currently, he is also geophysicist at GIM-Labs since 2019.
