Professor Chris Ballentine

Chair of Geochemistry

Department of Earth Sciences

Chris is the Chair of Geochemistry in the Department of Earth sciences and has a broad interest in groundwater interaction with hydrocarbon, helium, nitrogen and carbon-dioxide (CO2-sequestration) multiphase systems. He uses noble gas isotopic tracers to understand groundwater residence and the source of geogenic gases. He is the Oxford PI on a 5 year USGS initiative to identify the impact of historical hydrocarbon production on Californian drinking water supplies.

Prof. David Clifton

Associate Professor in Engineering

Department of Engineering Science

David Clifton is developing tools, based on machine learning methods, to (i) use sensor data from systems embedded in ‘smart handpumps’ to track the condition of the pump, and to estimate the aquifer level; and (ii) fuse data from many different sources (hydrogeological models, household surveys, the ‘smart pump’ network) to produce systems that predict risk to water security.
