Yves Guglielmi is a Geological Senior Scientist at the Lawrence Berkeley National Laboratory. His principal interests cover fundamental research in the hydromechanics of fractured and faulted rock. He focuses on the in situ understanding of the relationships between hydraulic, elastic and strength properties, rheology and induced seismicity of faults and fractures through field observation. Applications of his research concern giant rock landslides, and geo-energy (nuclear waste disposal, reservoir seal integrity and deep geothermal energy). He has been the Principal Investigator of several national and international programs on CO2 storage in deep reservoirs and on giant landslides in the European Alps.
