Geochemistry Fellows

About the Geochemistry Fellow Honor

In 1996, the Geochemical Society and the European Association of Geochemistry established the honorary title of Geochemistry Fellow, to be bestowed upon outstanding scientists who have, over some years, made a major contribution to the field of geochemistry. Recipients of the Goldschmidt, Patterson, EAG Science Innovation, Treibs, and Urey Awards become Fellows automatically.

Scientific excellence is a core value of both the Geochemical Society and European Association of Geochemistry, and it is our privilege, by rewarding it, to take a leading role in its definition. In awarding Geochemistry Fellows, our societies believe it is important to recognize the broad spectrum of scientific achievements that advance geochemistry. Excellence should not be limited to major discoveries and ideas that change paradigms, and not solely evaluated on the basis of the number of papers published in high-impact journals; the nominee's h-index and previously obtained distinctions; nor the amount of funding acquired. Instead, we recognize that scientific eminence, achievement, and impact also encompass sustained and proven contributions that create a dynamic environment essential for scientific progress.

Examples of these include:

  • improvements to infrastructure and techniques;
  • capacity building-especially in developing countries or emerging disciplines;
  • curation of sample collections and databases of long-term scientific significance;
  • exceptional editorial contributions;
  • communication of the intrinsic excitement of our field to the general public;
  • work with policy makers to ensure that their decisions are grounded in rigorous science;
  • training the next generation of geochemists;
  • and advancing ethics, inclusiveness, and social justice in science.

By recognizing the full diversity of the geochemical community and its many varied contributions we hope to provide a wide range of examples that young scientists can strive to emulate. The societies will accept nominations for the 2024 Fellows until October 31, 2023.

From early life to environmental sciences and Martian exploration, Karim Benzerara focused on how microorganisms form or degrade minerals, using a careful coupling of the tools of biology, Earth sciences and materials sciences. He combines exceptional experimental skills and scientific rigor together with an uncommon insight in the problems investigated. Karim also contributed actively to the scientific life of our geochemical community, being involved in EAG and GS activities and in the organization of major international meetings (EGU, Goldschmidt, EMC, IMA).

Antje Boetius

Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, Germany

Antje Boetius is an internationally outstanding marine microbiologist and geochemist. Her ground-breaking work includes the discovery of syntrophic microorganisms responsible for the anaerobic oxidation of methane in the seabed and the role of biogeochemical processes in the Arctic Ocean for the global carbon cycle and climate development. She is also an outstanding communicator of marine science through radio and television and in general science debates and has strongly contributed to the public awareness of the ocean and its role for our future climate.

Maud Boyet

University Clermont Auvergne, France

Maud Boyet has fundamentally and comprehensively interrogated the assumptions about making the Earth. This followed her discovery that the Earth is non-chondritic for the refractory, lithophile element system Sm-Nd for which the classic chondrite paradigm should best apply. Maud has long been an inspiring role model, not only for scientific excellence but also undemonstrative service to the geochemical community.

Elizabeth Cottrell

National Museum of Natural History, Smithsonian Institution, USA

Elizabeth Cottrell is recognized for her world leading contributions in the study of mantle processes, most notably those related to mantle oxidation state, work that has led to transformative scientific advances and catalyzed a renaissance in the field. She has also mentored a large group of young scientists, made important contributions to the community through curation of sample collections and databases, and is a passionate and gifted science communicator.

Andrew M. Davis

The University of Chicago, USA

Through his studies of evaporation/condensation processes in the solar nebula, early solar system chronology, and presolar grains and nucleosynthesis, Andrew Davis has broken new ground in the fields of geochemistry and cosmochemistry. The foundation for many of these studies has been development and creative use of novel instrumentation (SIMS, RIMS). Without any expectation of recognition or fanfare, he has been an exceptional scientific citizen, generously sharing his extensive knowledge and creative ideas, serving on numerous NASA committees, and providing his expert advice for sample-return missions.

Hailiang Dong

China University of Geosciences-Beijing

Hailiang Dong is recognized for his groundbreaking contributions to isotopic, microbial, and environmental geochemistry by pioneering the 40Ar/39Ar dating of clay diagenesis; discovering microbially catalyzed mineral reactions; unraveling the mechanisms of coupled elemental cycles; developing remediation strategies of contaminants and medical applications of clays; and serving as editor/AE for multiple journals and program manager/panel member for funding agencies.

Danielle Fortin

University of Ottawa, Canada

Danielle Fortin is recognized for her exploration of the microbe-mineral interface which has advanced our understanding of how microbial metabolism leads to geochemical and mineralogical consequences, like biosignature formation. Moreover, Danielle has been an active leader in geochemistry and creates a welcoming community for students and early career researchers.

Penelope L. King

Australian National University, Australia

Penny King's career highlights include sustained and proven work on the analysis of volatiles in igneous rocks and glass, innovations in mid-infrared analyses of geologic materials, influential contributions to the exploration of Mars, including as a Co-I on the MSL mission, and recent innovations in the study of gas-solid reactions.

Thorsten Kleine

Max Plank Institute for Solar System Research, Germany

Thorsten Kleine is recognized for ground-breaking new insights to the understanding of the origin and early evolution of our solar system using isotopes.

Daniel Ochieng Olago

University of Nairobi, Kenya

Daniel Olago is recognized for a distinguished career in which he has authored 178 peer-reviewed journal articles & reports, led several interdisciplinary geoscience research consortia, trained three dozen postgraduates, and represented Africa in a few global platforms (e.g. IPCC). He effectively employed geochemistry to solve complex environmental and water security challenges in the Horn of Africa.

Clive Oppenheimer

University of Cambridge (UK)

Clive Oppenheimer is recognized for innovations in remote sensing of volcanic gases and aerosol which have transformed the chemical surveillance of active volcanoes, and led to new and profound insights into the behaviour of degassing magmatic systems; for wider contributions to the understanding of the impacts of volcanism on climate, and the environment; and for his notable contributions to film, radio and popular writing that have reached audiences well beyond the realms of geoscience.

Clare E. Reimers

Oregon State University, USA

Clare Reimers is recognized for pioneering and sustained contributions to sea-floor geochemistry including organic matter cycling near the benthic interface, oxygen consumption, and sediment diagenesis, enabled by development and application of innovative geochemical technologies, along with extraordinary service to the seagoing science community.

Rosalind E. M. Rickaby

University of Oxdord, UK

Rosalind Rickaby is a world leader in developing novel proxies from marine carbonates to reconstruct climate and, more generally, Earth’s environment over geological time. Indeed, her research has informed us about the co-evolution of the geosphere and biosphere. Further, Rosalind Rickaby is also dedicated to outreach to school-children and non-specialist adults using various media, promoting an understanding of biogeochemistry and the role of the oceans in the Earth systems more broadly.

Myrna J. Simpson
