Sir Alexander Norman Halliday is a British geochemist and academic who is Director of the Earth Institute at Columbia University. He joined the Earth Institute in April 2018, after spending more than a decade at the Department of Earth Sciences at the University of Oxford, during which time he was dean of science and engineering. He is also a Professor of Earth and Environmental Sciences at Columbia University.
Geochemical modeling is the practice of using chemical thermodynamics, chemical kinetics, or both, to analyze the chemical reactions that affect geologic systems, commonly with the aid of a computer. It is used in high-temperature geochemistry to simulate reactions occurring deep in the Earth's interior, in magma, for instance, or to model low-temperature reactions in aqueous solutions near the Earth's surface, the subject of this article.
Miriam Kastner is a Bratislavan born American oceanographer and geochemist. Kastner is currently a Distinguished Professor at Scripps Institution of Oceanography at the University of California, San Diego.

Professor Kliti Grice is an organic and isotope geochemist known for her work in identifying geological and environmental causes for mass extinction events.
Katherine H. Freeman is a co-editor-in-chief of the peer-reviewed scientific journal, Annual Review of Earth and Planetary Sciences. She is also the Evan Pugh University Professor of Geosciences at Pennsylvania State University where her research interests are organic geochemistry, isotopic biogeochemistry, paleoclimate and astrobiology.
Frederick T. Mackenzie is an American sedimentary and global biogeochemist. Mackenzie applies experimental and field data coupled to a sound theoretical framework to the solution of geological, geochemical, and oceanographic problems at various time and space scales.
Gao Shan was a Chinese geochemist and academician of the Chinese Academy of Sciences (CAS). He was a professor of geochemistry at the China University of Geosciences (Wuhan).
Susan L. Brantley is an American geologist and geochemist who is Distinguished Professor of Geosciences at Pennsylvania State University. Her research dominantly studies interactions between fluids and minerals at low temperatures, biological reactions in water-rich fluids within soils, and the geochemical processes that convert rock into soil. However, among many other topics she has also published work on carbon dioxide emissions from volcanoes, and the environmental impact of shale gas extraction and nuclear waste disposal. During her career, Brantley has published over 200 research papers and book chapters, has been awarded academic prizes and fellowships by many of the world's leading geoscience societies, and has been described as "one of the leading aqueous geochemists of her generation."
Joel D. Blum is a scientist who specializes in isotope geochemistry and environmental geochemistry. He is currently a Professor of Earth and Environmental Sciences at the University of Michigan with additional appointments in the departments of Chemistry and Ecology and Evolutionary Biology. Blum has several named professorships including the John D. MacArthur, Arthur F. Thurnau and Gerald J. Keeler Distinguished Professorship. Blum is a past Co-Editor- in-Chief of Chemical Geology and Elementa, and is the current Editor-in-Chief of the American Chemical Society journal Earth and Space Chemistry.
