Executive Committee

The Executive Committee is comprised of the Theme Coordinators and Theme Leaders. This committee has two subcommittees: GSCO2 Functionality (Task Coordinators) and GSCO2 Science (Task Leaders). Each committee meets monthly. The Science sub-committee members are the Theme Leaders; meetings are attend by Theme Coordinators, too. The Functionality sub-committee members are the Theme Leaders. The Executive Committee meets in person semi-annually to provide an internal review of the management of the Center. This committee and sub-committees advise the Director directly.

Scott Frailey

Scott M. Frailey, PhD
University of Illinois, Urbana-Champaign

Dr. Scott M. Frailey is the Director of the GSCO2 and the chair of the Executive Committee. He provides scientific and technical leadership, as well as maintaining the functionality of the Center in terms of communication, collaboration, personnel assignments and recruitment of staff and advisory committee members. Scott's specific research is in the area of reservoir characterization that includes core analyses, well log analyses, and pressure transient analyses to provide reservoir rock properties to geocellular models for use in multiphysics flow and transport modeling.

Steve Whittaker, PhD
University of Illinois, Urbana-Champaign
Associate Director

Dr. Steve Whittaker is the Director of Energy Research & Development at the Illinois State Geological Survey, which is a part of the Prairie Research Institute at the University of Illinois. He leads a team with wide-ranging research interests in efficiencies around subsurface resources, including carbon capture and storage. He was previously based in Perth, Australia, where he was Research Group Leader for Reservoir Dynamics with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), working on deploying carbon storage technology at the industrial scale in Australia and globally. Steve also serves as Chair of the TC265 committee developing ISO 27914, an international standard for geological storage of CO2. Previously, he was Principal Manager for Geologic Storage of CO2 at the Global CCS Institute in Canberra, Australia, and Chief Technology Manager at the Petroleum Technology Research Centre in Canada. In the latter position, he managed a program studying storage and monitoring of CO2 injected into a depleting oil field for enhanced oil recovery at Weyburn, Saskatchewan, which is among the world’s largest monitored CO2 injection sites. Steve is a geologist with a PhD from the University of Saskatchewan, Canada, and has worked in petroleum and carbon storage related fields for more than 20 years.

Charles J. Werth

Charles J. Werth, PhD
University of Texas, Austin
Theme Leader

Dr. Charles J. Werth is a Professor and Bettie Margaret Smith Chair of Environmental Health Engineering in the Department of Civil, Architecture, and Environmental Engineering at the University of Texas at Austin. He joined the UT faculty in August or 2014, after spending 17.5 years on the faculty at the University of Illinois at Urbana-Champaign. Dr. Werth's research and teaching focus on the fate and transport of pollutants in the environment, the development of innovative catalytic technologies for drinking water treatment, and the mitigation of environmental impacts associated with energy production and generation. Dr. Werth is a Wiley Research Fellow at the Department of Energy’s Environmental Molecular Science Laboratory, and a member of the USEPA's Science Advisory Board. Past recognition includes an Editors Choice Best Paper Award from Environmental Science and Technology (2nd in the category of Technology), recognition for the most cited paper in Journal of Contaminant Hydrology since 2008, a Humbolt Research Fellow Award, a National Science Foundation CAREER Award, and a BP Award for Innovation in Undergraduate Instruction. Dr. Werth received a B.S. in Mechanical Engineering from Texas A&M University, an M.S. and Ph.D. in Environmental Engineering from Stanford University, and a Ph.D. minor in Chemistry from Stanford University.

His areas of expertise include wave propagation modeling and testing, material nondestructive testing and imaging, and innovative sensing technologies.


Volker Oye

Volker Oye, PhD
Theme Leader

Dr. Volker Oye graduated Goethe University Frankfurt, Germany in 2000 (Diploma thesis on true amplitude migration) and made a PhD at University of Oslo and NORSAR in 2004 on Observation and Analysis of Microearthquakes. In the following years Oye worked on induced and triggered microseismicity in various environments such as mines, hydrocarbon reservoirs, geothermal reservoirs, CO2 storage and also on lab-scale acoustic emissions. Since 2013 Oye is head of the Department on “Earthquakes and the Environment” at NORSAR.

Pore-scale Pressure Transmission

Albert Valocchi

Albert Valocchi, PhD
University of Illinois, Urbana-Champaign
Theme Leader

Albert J. Valocchi is the Abel Bliss Professor in the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign. He has been on the faculty at Illinois since 1981. Valocchi’s research focuses upon computational modeling of pollutant fate and transport in porous media, with applications to groundwater contamination, geological sequestration of carbon dioxide, and impacts of model uncertainty on groundwater resources management. He received his B.S. in Environmental Systems Engineering from Cornell University in 1975 and did his graduate studies at Stanford University in the Department of Civil Engineering, receiving his M.S. in 1976 and Ph.D. in 1981. In 2009, he was recognized as a Fellow of the American Geophysical Union.

Reservoir-scale Geology

Dustin Sweet

Dustin Sweet, PhD
Texas Tech University
Theme Leader

Dr. Dustin E. Sweet holds a PhD (2009) in Geology from the University of Oklahoma and a MSc (2003) and a BSc (2000) in Geology from Boise State University. Upon completion of his PhD, Dr. Sweet worked as an exploration geologist at Chevron Energy Technology Company until he joined the faculty at Texas Tech University in the fall of 2011. During his time at Chevron, Dr. Sweet’s chief role was developing new plays and prospects in new venture opportunities, largely in West Africa. Dr. Sweet’s areas of expertise include process sedimentology, chemical weathering in soil profiles, and stratigraphy. He uses those skills to unravel climatic and tectonic history from the sedimentary record, predominantly within late Paleozoic basins in the United States and Quaternary strata on the Southern High Plains. He currently serves as leader of the Geology Theme for the Center for Geologic Storage of CO2, where he brings his sedimentologic and weathering skills to bear on understanding the character of the interval near the great unconformity in the mid-continent. He enjoys camping with his wife and three boys wherever late Paleozoic strata are exposed.
