Sigurður (Siggi) Reynir Gíslason
EAG Past-President
Sigurður (Siggi) Reynir Gíslason received his PhD in geochemistry from the Johns Hopkins University, under the supervision of Hans P. Eugster. He is a Research Professor at the Institute of Earth Sciences, University of Iceland. He is the chairman of CarbFix (carbfix.com), the initiative to store carbon in basaltic rocks. Siggi’s major scientific contributions are: 1) measurement of the dissolution rates and dissolution mechanisms of volcanic glasses as a function of glass composition, aqueous solution composition and temperature, 2) field and laboratory experiments related to mineral storage of CO2 in basaltic rocks, 3) quantifying the chemical/physical erosion rates of basaltic terrains and their contribution to the global carbon cycle and 4) measuring the environmental effects of volcanic eruptions.
