After receiving a B.Sc. in petrology and mineralogy from Tohoku University, Masaki Akaogi earned a Ph.D. in geophysics from the University of Tokyo. Subsequently, he worked as an assistant professor and as an associate professor in the Department of Earth Sciences, Kanazawa University. He was a postdoctoral fellow in the Department of Chemistry, Arizona State University in the early 1980s, and was a visiting scientist in the Department of Geosciences, Princeton University. From 1990 to 2021, he was a full professor in the Department of Chemistry, Gakushuin University, where he is currently an emeritus professor. He served as an editor of Physics and Chemistry of Minerals (Springer) from 1997 to 2005. His research interests include high-pressure phase equilibria and thermodynamic properties of silicates and related compounds with applications for clarifying mineralogy, structure, and dynamics of the Earth s interior and for synthesis of new inorganic materials. Dr. Akaogi is a fellow of the Mineralogical Society of America and of the Japan Geoscience Union. He has received awards from the Mineralogical Society of Japan and the Japan Society of High Pressure Science and Technology.
