Elizabeth Akonobea Appiah is a PhD candidate in Petroleum Engineering at New Mexico Institute of Mining and Technology. Her research focuses on geologic carbon storage, CO₂ mineralization in basalt, fluid rock interactions, reactive transport and reservoir engineering. Her work integrates laboratory flow through experiments under reservoir conditions with petrophysical and geochemical characterization and reservoir modeling to investigate CO₂ storage performance and long term mineralization. She also has industry experience in mineral processing and metallurgy, including flotation, comminution, gold processing and process optimization. Her broader research interests include carbon capture, utilization and storage (CCUS), reservoir engineering, mineral processing and sustainable energy technologies.
