EPFL

EPFL is Europe’s most cosmopolitan technical university. It welcomes students, professors and collaborators of more than 120 nationalities. EPFL has both a Swiss and international vocation and focuses on three missions: teaching, research and innovation. EPFL collaborates with an important network of partners, including other universities and colleges, secondary schools and gymnasiums, industry and the economy, political circles and the general public, with the aim of having a real impact on society.

Prof. Lecampion's group works on fundamentals & applied research problems associated with sub-surface projects with a strong focus on the energy transition (deep geo-thermal energy, CO­₂ storage, Gas production & storage, radioactive waste storage). We are notably working on the multi-physics coupling occurring during the rupture of geomaterials, combining theory, numerical modeling and experiments. Our research aims at both improving industry practices and providing to decision makers, regulatory bodies and the public expertise on fundamental and practical problems related to Geo-Energy.

The Geo-Energy Lab at EPFL, led by Prof. Lecampion, has opportunities to pursue a fully funded PhD within the EPFL doctoral program. Our research addresses problems in the mechanics of fluid-saturated geomaterials, in particular the growth of fluid-driven discontinuities in the form of fractures and faults. Examples of applications span the fields of geo-energy (Geothermal energy, CO₂ geological storage), environmental engineering hydrology (radioactive waste management), geotechnical engineering (landslides, rock falls), seismology (fluid induced seismicity) and volcanology (diking events).

This doctoral research aims to strengthen the connection between observations and theoretical models of fluid-induced ruptures across laboratory and field scales. A central objective will be to jointly analyze the seismic and quasi-static (aseismic) signals associated with rupture processes. At the laboratory scale, the goal will be to integrate distributed fiber-optic strain sensing into a true-triaxial experimental setup designed for decimeter-scale fluid-driven fracture propagation. This addition will complement an existing high-resolution acoustic imaging system, enabling acquisition of unprecedented multimodal datasets. In parallel, inverse-problem modeling will be developed to interpret these measurements within the framework of the mechanics of fluid-driven fracture. The methodologies and models established in the laboratory will also be evaluated at field scale through external collaborations using existing datasets.

This research requires interests in the theory & numerical modeling of hydromechanical fracture problem as well as the geophysical response of geomaterials to fracture.
