The BGeoSys group includes academics, post-doctoral, Ph.D. and technical staff with expertise in a range of research fields from the biogeochemistry of continental and marine systems, the kinetics of water-rock-microorganisms processes to the modelling of the Earth system. Our approach encompass experimental,modelling and field work covering an large spectrum of temporal (seconds to billion years) and spatial -(nanometer to the global) scales. We are focusing our efforts on the carbon and nutrients cycles and on their role in shaping the present and past climates of the Earth.
