Aaron Cahill

Aaron Cahill is an Assistant Professor at Heriot-Watt University's Global Research Institutes and The Lyell Centre. His research focuses on environmental science, hydrogeology, and energy engineering, with a particular emphasis on mitigating methane leakage, assessing risks associated with carbon capture and storage, and understanding fugitive gas migration from oil and gas wells. His work contributes to UN Sustainable Development Goals related to climate action and responsible consumption.

His research spans locations including Scotland's North Sea, British Columbia, and the UK. Key areas include well integrity assessment, subsurface gas migration dynamics, and environmental impacts of energy infrastructure. Collaborations with institutions in Canada and the UK highlight his international reach in addressing geoscience challenges.

Recent studies explore innovative solutions like soils-based oxidation for methane mitigation and petrophysical approaches to evaluate gas migration risks. Cahill's interdisciplinary work bridges environmental science, engineering, and policy to advance sustainable energy practices while safeguarding ecological systems.
