Naohiro Yoshida (Senior Advisor)

Tokyo Institute of Technology

Naohiro Yoshida is a Professor in two environmental departments and also a Principal Investigator of Earth-Life Science Institute at Tokyo Institute of Technology, Tokyo and Yokohama. He is one of the leading biogeochemists in the field of global environmental analysis with isotopes of bioelements. He has introduced the isotopomers and isotopologues, with MIF, Clumped, and PSIA, as powerful tracers to help reduce uncertainties regarding the biological, chemical, physical, and anthropogenic source and sink processes of environmental molecules especially global warming related species. He has published over 200 papers including 8 published in Nature and Science, 14 patents, 30 book chapters, edited 6 books, been invited for keynote talks by a number of international scientific conferences. He was recently elected as a Science Advisory Panel member of GEO-6, UNEP. When he was the President of GSJ, the Goldschmidt Conference 2016 was decided to be held in Yokohama, and the MOUs among GS, EAG, and GSJ were signed.

Kyoto University

Takafumi Hirata is internationally recognized as one of the pioneers in elemental imaging and isotope ratio analysis using the LA-ICPMS technique. He developed new analytical technique for highly localized measurements for trace elements. In 2009, he moved to Kyoto University to continue his research as a tenured Professor. He developed two important application for the Geochemistry : (1) high-spatial resolution dating method using LA-ICPMS technique, and (2) age determination for very young zircon samples through the correction of initial disequilibrium. Moreover, he began transferring analytical tools for spatially resolved elemental and isotopic analysis originally designed for geoscience applications to open up new doors to biomedical research. He was invited to join the Japan Metallomics Forum as a board member. He visited University of Pau, France, as a visiting Professor, to extend his knowledge for elemental imaging from biochemical samples. Recently, he developed new analytical technique to improve both the spatial resolution and the precision in the age determinations using the newly developed ion collector (Daly ion counter). With the combination of the Daly collector and newly developed multi-spot ablation technique using Galvanometric optics, precision and accuracy of the age determinations from various minerals, including carbonate, phosphate or other minerals can be made.

Japan Agency for Marine-Earth Science and Technology

Naomi Harada received a PhD in Organic Geochemistry from Nagoya University. She is also leading the Marine Ecosystem Dynamics Research Group of RCGC, and Arctic Marine Ecosystem Research Unit of Institute of Arctic Climate and Environmental Research She has investigated to understand changes in the surface water condition (temperature and salinity), biological productivity, and intermediate-deep water ventilation over the orbital and millennial time scales based on marine sediment cores records from Okhotsk and Bering Seas and western North Pacific. Her current research interest is to understand productivity changes associated with climate change by time-series sediment trap experiments in the western subarctic North Pacific and Arctic Ocean. She is science steering committee of Ecosystem Studies of Sub-Arctic and Arctic Seas (ESSAS), which is the regional program of IMBER and is currently serving the committee of Resilience and adaptive capacity of Arctic marine systems under a changing climate (RACArctic).

My playground is somewhere between stable isotope and spectroscopy. Our recent focus has been identifying the source of methane form clumped isotopologue (13CH3D) and the origin of sulfur mass-independent fractionation signals to constrain early Earth’s climate.

ETH Zürich

Derek Vance is Professor of Geochemistry at ETH Zürich, having moved here from the UK in 2012. He has worked in a number of areas of geochemistry but is currently most interested in the geochemical evolution of the surface Earth, from the Archean to the present. He uses established and novel geochemical and isotopic tracers to investigate and characterize modern global oceanic biogeochemical cycles, to better understand material fluxes at the surface of the Earth, and in particular their impact on the chemistry and biology of the ocean.

My research evolves around understanding the origin and evolution of continents, from determining the composition of the continental crust through time and the implications of this composition for crust formation and evolution, to understanding the composition and origin of the continental lithospheric mantle. I am currently a Distinguished University Professor in the Department of Geology at the University of Maryland. In January 2016 I will be moving to the Department of Earth Science at the University of California at Santa Barbara.

Daniela Rubatto is a Professor at the Institute of Geological Sciences at the University of Bern, Switzerland. She recently moved there after a long period at the Australian National University in Canberra, Australia. She obtained her degree at the University of Torino, Italy, and a PhD at the ETH in Zürich, Switzerland, where she first worked on high-pressure rocks. She combines geochronology and oxygen isotopes with trace element geochemistry and petrology in studying the behaviour of accessory minerals during metamorphism, particularly at high pressure and temperature. This research has integrated advanced analytical methods (e.g. SHRIMP ion microprobe) with experimental petrology and field studies to investigate rates of metamorphic processes, mountain building and the migration of fluids in the crust.
