Jin Luo obtained his Bachelor and Master degree from China University of Geosciences (CUG, Wuhan) with major in Geotechnical Engineering. He subsequently did a PhD at the University of Erlangen-Nuremberg in Germany and graduated in 2014. His doctoral work was on ground source heat pump (GSHP) system installed in Nuremberg city. Geothermal borehole field of the GSHP system was investigated via system monitoring, field tests and numerical simulation.

He is currently an Associate professor in Faculty of Engineering, China University of Geosciences (CUG) since 2014. His work focuses on thermo-mechanical behaviors of energy piles and geothermal potential evaluation of Hot Dry Rock (HDR) reservoir, as well as chemical investigation of the hydraulic properties of fractured granite. Dr. Jin Luo is currently a visiting scholar at UC Berkeley and he is working on thermally induced geo-mechanical and environmental issues during geothermal exploitation.
