A brief biography of each candidate is presented below. Click on a candidate's name for more information.
International Secretary
The International Secretary is responsible for outreach to scientists and students in countries that are under-represented in the society's membership, as well as communication with international geological organizations. This is a three-year term of service.
(Select ONE)
MAGALI ADER
Magali Ader is Professor of Geochemistry at the Institute of Earth Physics of Paris, France. Her research interests focus mainly on understanding controls on stable isotope compositions in sedimentary rocks and fluids. This has led her to address several aspects of Earth Sciences including the evolution of carbon and nitrogen biogeochemical cycles through time, bacterial vital effects, fluid-rock interactions in CO2 storage sites and solute transport properties in sedimentary basins.
YEMANE ASMEROM
Yemane Asmerom is a professor of isotope geochemistry at the Department of Earth & Planetary Sciences, the University of New Mexico, where he founded and is the director of the Radiogenic Isotope Laboratory. Over the last decade, he has been part of the leading edge in technical (e.g. half-life determinations, ionization techniques, chemical procedures, and instrumental configurations), conceptual and applied developments in uranium-series isotope geochemistry. His research interests range from dynamics and time-scale of climate change to the evolution of the solar system. He is a Geochemical Fellow and Fellow of the Geological Society of America.
Secretary
The Secretary maintains the Bylaws, records Board votes and meeting minutes, and serves as the Geochemical Society representative on the Elements Executive Council. This is a three-year term of service.

TAKAHIRO TAGAMI
Takahiro Tagami is a professor at the Division of Earth and Planetary Sciences, Kyoto University, Japan. His current research interests are (1) low temperature thermochronology of mountain building and fault motions using fission-track, (U-Th)/He, and other techniques, (2) Reconstruction of ancient volcanism using unspiked K-Ar and other techniques, and (3) Paleoclimate reconstruction using analyses of speleothems and tree rings. To conduct these interdisciplinary studies, he is involved in the GS and other geo-scientific societies.
ALEXANDRA "SASHA" TURCHYN
Alexandra (Sasha) Turchyn, a University of Cambridge Reader in Biogeochemistry, is a sedimentary isotope geochemist whose research seeks to understand how the carbon cycle works both now and over Earth's history. Her research focuses on how the microbial biosphere (bacteria and archaea) impact the carbon budget in sedimentary environments and how this biology may have functioned early in Earth history. She studies a range of modern and past processes and environments and how they are recorded in the sedimentary rock record. She has been a member of the Geochemical Society since her PhD, and attended nearly every Goldschmidt, as a presenter, session chair, and theme co-chair.
Treasurer
The Treasurer maintains the financial records of the society, ensures compliance with tax filing regulations, and chairs the Finance Committee. The Treasurer is elected for a three-year term.

SAM SAVIN
Sam Savin has applied stable isotope techniques to a wide range of problems related to the sedimentation, diagenesis and low-grade metamorphism of siliclastic sediments, and to weathering and soil formation. He has also worked on the reconstruction of paleoclimatic and paleoceanographic conditions of the past 100 million years, based on carbon and oxygen isotopic distributions in planktic and benthic foraminifera. For a number of years, in collaboration with physician colleagues, he used stable carbon isotopic tracers to study metabolic processes in human infants and mothers. In recent years he has also been active as an academic administrator, serving as Dean of Arts and Sciences at Case Western Reserve University and Provost at New College of Florida. Sam is now retired and consults on geochemical, environmental and administrative matters. He is a Geochemical Fellow.
Non-Officer Director
Non-Officer Directors participate in Board discussions and serve on the Board as voting members.This is a three-year term of service. In order for the Board membership to reflect the regional diversity of the Society membership, this year requires election of one officer from Europe (Region 2) and one from Africa, Asia, Australia, or South America (Region 3).
Director - Region 2

MICHAEL KOMAREK
Michael Komárek is currently Full Professor and Head of Department of Environmental Geosciences at the Czech University of Life Sciences Prague, Czech Republic. His research interests include mainly the biogeochemistry of metals and metalloids in soils, investigation and modeling of adsorption mechanisms and environmental isotope geochemistry. In 2012, he obtained a Fulbright Scholar fellowship to Western Michigan University, USA. In the period of 2009-2014, he was a visiting professor at the University of Limoges, France.
TAMSIN MATHER
Tamsin Mather is a volcanologist at the University of Oxford, UK where she has been on the faculty since 2006. Her research explores the many and diverse ways in which volcanoes have interacted with Earth's environment. This has led to collaborations with a broad range of geochemists working from mantle to ionosphere and beyond. She recently served as a theme leader for Volcanoes and Hazards at Goldschmidt 2016 and she sits on the AGU Committee on International Participation, the Natural Environment Research Council Science Board in the UK, and serves as an editor of Earth and Planetary Science Letters.
Director - Region 3

YOKO FURUKAWA
Yoko Furukawa is a Science Director at the US Office of Naval Research Global in Japan. Her primary technical areas of expertise are in oceanography and geosciences, while her portfolio also includes autonomy and unmanned systems, as well as synthetic biology. She served as a member of the technical committee (STC) for the SERDP Environmental Restoration Program Area, and currently serves as the Alternate Councilor for American Chemical Society Division of Geochemistry. She is the Co-Editor in Chief for the Division's official journal, Geochemical Transactions.
CLAUDINE STIRLING
Claudine Stirling is an Associate Professor in the Department of Chemistry and jointly Director of the Centre for Trace Element Analysis at the University of Otago in New Zealand. As an isotope geochemist, Claudine's research has focused on the geochemical analysis of the U-decay series isotopes, as well as the non-traditional stable isotope systems, with emphasis on technique development by MC-ICPMS and with applications in paleoclimatology, paleoceanography, and cosmochemistry. Claudine is a member of the Geochemical Society and an Associate Editor of Geochimica et Cosmochimica Acta.
