Dimitri Sverjensky was born and raised in Sydney, Australia. An early interest in bird-watching, together with a love of the outdoors, lead to the study of geology at Cranbrook School. There, as a teenager, he first learned the formulas of complex minerals, such as tremolite, under Frank Tebbutt. Subsequently, at the University of Sydney, he was trained in Crystallography by Ian Threadgold. Under the influence of Dal Swaine and Ron Wilkins, it became clear to him that he wanted to pursue the combination of geology and chemistry, i.e., geochemistry.
This interest in geochemistry led him to the PhD program at Yale University, where he worked with Danny Rye and Brian Skinner, and was also greatly influenced by Bob Berner and the late Phil Orville and Karl Turekian. His PhD research investigated the origins of base-metal sulfide ore deposits in sedimentary rocks and the origins of fluids in sedimentary basins. His first position after graduating in 1980 was at Lawrence Berkeley Laboratory studying oil-field brines. While there, he started a collaboration in theoretical geochemistry with the late Harold C. Helgeson at the University of California, Berkeley, an association and friendship that lasted 27 years. After a three-year stay at SUNY Stony Brook as an assistant professor, he was hired in 1984 by Johns Hopkins University where he has been ever since.
Over a period of more than 30 years, Sverjensky’s research interests in geochemistry evolved from economic geology, including the origins of sediment-hosted ore deposits and the chemistry of sedimentary basinal fluids, to high temperature and pressure aqueous solution chemistry (collaborating with H.C. Helgeson, E.L. Shock, and J.J. Hemley) to the geochemistry of the mineral-water interface. The theoretical advances made in these areas of research are now being applied in three new areas:
(1) Following a sabbatical in 2005, Sverjensky started a collaboration with Robert Hazen and colleagues at the Geophysical Laboratory of the Carnegie Institution of Washington in Astrobiology—specifically addressing the role of mineral-water interfacial reactions in the origin of life and the role of hydrothermal fluids.
(2) A second closely related line of research investigates the surface environments on early Earth using theoretical models of weathering and element mobility. These studies complement related studies of mineral evolution on Earth.
(3) During his most recent sabbatical in 2012, Sverjensky opened a new field of research into the role of water in the deep Earth. This research involves studying the role of fluid-mineral interactions in the Earth’s deep carbon cycle in a collaboration with Isabelle Daniel (Lyon) and Craig Manning (UCLA) through the Deep Carbon Observatory. Current topics include the origins of fluids in diamonds, the species and transport of carbon, sulfur and nitrogen in subduction zones, and the role of fluids in oxidation of the mantle wedges.
