Mateo Acosta has successfully defended his PhD

Mateo's PhD entitled, “Experimental studies of hydro-mechanical couplings in Enhanced Geothermal Reservoirs“, studied 1) how mechanical deformation affected fluid transport in intact and faulted rock, and 2) the effect of fluid pressures on earthquake nucleation and propagation. All under realistic conditions. His studies are particularly relevant for deep geothermal reservoirs where the main technical issues today are i) predicting fluid injection/extraction and ii) understanding induced seismicity. Mateo is now a post-doc at Caltech, USA. We wish him all the best!
