Tina Roberts-Ashby, Ph.D.

Dr. Roberts-Ashby began her professional career as a geologist with the Florida Geological Survey in 2002, followed by eight years in the environmental consulting industry working as a project manager and hydrogeologist in Florida and the Micronesia region. She joined the USGS in January 2011, working primarily on investigations and assessments of petroleum systems and carbon dioxide (CO2) storage resources throughout the U.S., with a major research focus on the Gulf Coast and Florida; she continues to conduct research in these areas to date.

In her current position as Center Director, Dr. Roberts-Ashby manages a team of scientists whose work focuses on comprehensive, interdisciplinary research, assessments, and surveys of the origin, occurrence, distribution, quantity, and composition of oil, gas, coal, minerals, and associated deposits. Additionally, this team assesses impacts to the environment due to anthropogenic activities associated with energy and mineral resource exploration, development, and production, and investigates the potential reuse of byproducts and wastes generated through energy and mineral production and extraction.

Dr. Roberts-Ashby's areas of research interests and expertise are carbonate sedimentology and diagenesis; reservoir characterization; CO2 sequestration–site characterization, storage capacity assessment, modeling; hydrogeology; aqueous geochemistry; reactive transport modeling; and geophysical interpretations.
