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.
