Research Interest:<\/strong> Mitchelle is an MSc student in Geoscience at the University of Calgary, focusing on integrated subsurface systems and their applications in carbon capture, utilization and storage (CCUS), critical mineral recovery, and produced-water management. Her research explores the potential of pre-injection brine extraction as a pressure-management strategy for geological CO\u2082 storage, with particular interest in the feasibility of mineral recovery, especially lithium, and the sustainable utilization of extracted brine.
Her work examines the interactions between geological characteristics, subsurface fluid behaviour, mineral recovery, and water-management pathways.
