My research interests are targeted at using natural rocks across the United Kingdom as a feedstock for long term carbon dioxide (CO2) removal by storing the CO2 inside carbonate minerals. I am interested in understanding how natural rocks in their current form (e.g., outcrops, cliff faces, etc) are currently sequestering different sources of carbon. Following this, I am interested if waste rock from quarries can be used as a carbon remediation feedstock, rather than letting them sit for long periods of time with no alternative purpose.

My research explores the use of mafic, intermediate, and felsic rocks as feedstocks for CO2 sequestration. This study will help determine what factors may lead to CO2 mineralization in rocks that have previously been ignored in this field of work. This will help further understand the fundamentals of carbonation reactions and will have further implications for the development of carbon capture and storage technologies that reverse the damaging effects of climate change.
