My research area is in situ mineral CO2 sequestration in the Samail Ophiolite aquifer in the Sultantate of Oman. The Samail Ophiolite aquifer is a site of exceptionally well-developed, naturally occurring in situ CO2 mineralization and serves as a natural analog for an enhanced process. My work involves characterizing the chemistry and hydrology of the peridotite aquifer system and reactive transport modeling of CO2 mineralization in the subsurface. This includes modeling both the natural process and how it could be enhanced, e.g., by CO2 injection. CO2 sequestration will play a critical role in mitigating global climate change as we seek to reduce CO2 emissions to the atmosphere, and in-situ mineralization promises to be a safe and permanent mechanism for storing CO2.
