Ian leads the Earth Systems and Environment group at the Bureau. For the last 4 years, Ian has been working on policy, as well as legal and technical aspects of carbon management in the context of CO2 enhanced oil recovery and sequestration in brine reservoirs. Ian was the geologic sequestration lead for the FutureGen Texas Team and was responsible for putting together the Environmental Information Volume (EIV) that formed the basis for ES for the two Texas FutureGen sites. Ian has given numerous talks at national conferences on gasification technologies and CO2 sequestration, as well as sequestration as a part of EOR.
Ian's current research interests are in science-based regulatory frameworks for CO2 sequestration, geomechanical and fluid-flow modeling of faults and seals in engineered brine reservoirs, and risk assessment for CO2. Ian is the co-PI of a $38-million DOE-funded project to study 1 million tons/year CO2 injection into the water leg of an EOR project at Cranfield field, Mississippi.
Ian came to the Bureau after working for 10 years as a Scientist Manager at the Virginia Department of Mines, Minerals, and Energy—Division of Mineral Resources. As a geology professor, Ian taught at Southern Methodist University in Dallas, Texas, and at Washington University in St Louis, Missouri.
