Brief Introduction
Dr. LIU Jinfeng obtained his Ph.D. degree in the field of Earth Sciences in Utrecht University, The Netherlands. His Ph.D. thesis entitled “Mechanical effects of sorption processes in coal and implications for coalbed methane recovery”. His expertise and research interests involve effects of stress-strain-sorption/reaction processes on transport properties of rocks in relation to geo-energy recovery and CC(U)S, mechanical and transport of rocks at high pressure and temperature, coupling between geomechanics, reaction and transport in rocks under crustal conditions, and risk assessment. His current research focuses on subsurface carbon mineralization, and fault frictional behavior in context of induced seismicity.
