Rodolphe Lescoutre – Researcher and Consultant @ M&U sas

“As a researcher and consultant at M&U sasu, his objective is to determine the 3D architecture of (inverted) rift basins using seismic interpretation together with geological and geophysical datasets”

Short bio

Rodolphe Lescoutre first joined M&U sasu in August 2019 to undertake seismic interpretation and structural modelling in 3D for exploration purpose in South America. After an experience as researcher at the University of Uppsala (Sweden), he went back to M&U sasu in November 2022. 

He received his Ph.D. from the University of Strasbourg (France) in 2019 in the framework of the OROGEN project. His research dealt with the 3D structural architecture and tectonic evolution of the Western Pyrenees (Mauléon to Basque-Cantabrian basins), from rifting to continental collision, using mainly seismic interpretations and field observations. Another aspect of his Ph.D. aimed to investigate the thermal evolution of asymmetric hyperextended margins. During his experience at Uppsala University, Rodolphe worked as on-site geologist (core description and core logging) for two scientific drilling (ICDP and I-EDDA) in Sweden. Borehole data, seismic interpretations and forward magnetic and gravity modelling were used to propose a 3D geological model of central-western Sweden and to understand orogenic deformation in external cratonic domains.

Rodolphe holds a bachelor’s degree and a master’s degree in structural geology and tectonics from the University of Strasbourg.
