Sigurdur Gislason (EAG Vice-President)

Sigurdur (Siggi) R. Gislason is a Research Professor at the Institute of Earth Sciences (IES), University of Iceland. He has been a member of the Institute since 1985. He received his PhD in geochemistry from the Johns Hopkins University in 1985, under the supervision of Hans P. Eugster. There he studied the fundamentals of thermodynamics and kinetics of water-rock interactions, applying both field observations and experiments in the laboratory. Over the past decades, Siggi’s research group at IES has focused on four fields, in chronological order: 1) field measurements of the chemical and physical erosion rates of basaltic terrains and their role in the global carbon cycle; 2) experimental quantification of the dissolution rates and mechanisms of volcanic glasses as a function of glass composition, aqueous solution composition and temperature; 3) assessing the environmental pressure from volcanic eruptions on surface waters, using both field observations and laboratory experiments; and 4) mineral storage of CO2 in basaltic rocks. This last research field has been within the CarbFix project, where natural analogues, laboratory experiments, reactive transport models, and large-scale field experiments have been applied to show that CO2 can be mineralised safely and rapidly. During the pilot project of the field phase, injected CO2 was mineralised within two years of injection into reactive basaltic rocks at 20-50°C. The CarbFix method for capturing and storing CO2, and gas mixtures such as CO2 and H2S, has now been taken to an industrial scale at the Hellisheidi geothermal power plant in Iceland.

Bernard Marty (EAG President)

Bernard Marty is a Professor of geochemistry at the Ecole Nationale Supérieure de Géologie, Université de Lorraine, and researcher at the Centre de Recherches Pétrographiques et Géochimiques (CRPG, UMR 7358 CNRS-UL), Nancy, France. His is interested in the geochemistry and cosmochemistry of volatile elements, notably stable isotopes and noble gases. Topics include stable isotope variations in the solar system, processes of planet formation, the origin(s) of terrestrial water and other volatiles, the geodynamical cycle of these elements, and the evolution of the atmosphere from the Hadean eon to Present. Besides mantle geochemistry, Bernard is involved in space missions such as Stardust (return to Earth of cometary grains), Genesis (analysis of the isotope composition of the solar wind), Rosetta (in situ analysis of cometary volatiles), and others. Bernard gained a Ph.D. in physics at the University of Toulouse, France, and a Doctorat d’Etat in geochemistry at Université Pierre and Marie Curie, Paris. Bernard was co-chair of the Meteoritical Society meeting in Nancy in 2009, and chair of the Goldschmidt Conference in Prague in 2011, serving as EAG Goldschmidt Officer from 2009 to 2014. He was EAG Vice-President in 2015-2016 and currently serves as EAG President for 2017-2018.

Rizlan Bernier-Latmani (Grant Program)

Sami Mikhail (Student Program)

Dr. Mikhail is a Senior Lecturer (Associate Prof) in Earth Sciences at the University of St Andrews. The motivation behind Dr. Mikhail’s research is to understand how the interior of a planet affects and controls the composition of its surface and to long-term habitability. Dr. Mikhail’s approach combines investigations of natural samples with high-pressure and -temperature experiments and theoretical models. To date, this approach has been applied to a diverse range of projects such as the source of Icelandic volcanism, diamond-formation in the deep Earth, and more recently, on linking mantle processes to atmospheric chemistry on Earth, Mars, Venus, and exoplanets.
