Mouadh Addassi, Ph.D.

Research Scientists

Research Scientist



I am a dedicated researcher with a broad knowledge base in applied mathematics, petroleum engineering, mechanical engineering, and data science. I have a solid understanding of reactive subsurface systems and how to simulate these using state-of-the-art computational tools accurately. My primary role is to study carbon mineralization potential in local subsurface mafic and ultra-mafic rock formations along the Red Sea coast. 

Research Interests

I am interested in developing cutting-edge multi-phase reactive flow models to study CO2 sequestration in basalts and applying them to predict and optimize the storage capacity of local sites. The modeling will be verified by experimental work. The combination of experimental investigations and numerical modeling should provide better understanding of the potential of CO2 sequestration in local basalt sites.
