Biography

Inci Demirkanli is a senior scientist at Pacific Northwest National Laboratory with experience in analytical and numerical modeling of subsurface flow and transport with applications in remediation research and radionuclide mobility in the vadose zone and in subsurface energy and storage systems, such as geologic sequestration of CO2, enhanced oil recovery, and hydraulic fracturing. She has managed and participated in large projects, providing technical and programmatic support to the U.S. Department of Energy's (DOE’s) Hanford Site for characterization and monitoring of contaminants, assessment and implementation of remediation technologies, and remedy impacts and optimization. In addition to supporting Hanford Site work, she also provided technical and programmatic support to the Environmental Protection Agency (EPA), particularly for underground injection related issues such as rulemaking for the development of federal requirements for geologic sequestration of CO2. In addition to authoring a number of journal articles, a book chapter, and technical reports, she has also authored several national guidance documents for geologic sequestration of CO2, covering areas such as site characterization, the use of numerical modeling for determining project risk areas, and testing and monitoring. She is also one of the authors of the EPA’s Hydraulic Fracturing Drinking Water Assessment Report delivered to Congress in 2017 and the Interagency Task Force Report on Carbon Capture and Storage delivered to President Obama in 2010.
