Events

  • Sponsor Seminars

  • Training Events

    These are scheduled events to help delegates test out the tools and platform we will be using for the Q&A and other events at the conference.

  • Workshops

    Our workshop program provides training and teaching in topics across geochemistry and related fields. We are currently liaising with the workshop organisers to ascertain if any workshops can become virtual. Any updates will be added to this page.

Role functions

Details for: Yusuke Yokoyama


Yusuke Yokoyama is a Professor at the Atmosphere and Ocean Research Institute, The University of Tokyo. He is also appointed at the School of Science (Department of Earth and Planetary Science) as well as at Graduate School of Arts and Sciences, College of Arts and Sciences (Graduate Program on Environmental Sciences). He received his PhD from The Australian National University (2000), where he conducted his study at the Research School of Earth Sciences. He then moved to the Space Sciences Laboratory, University of California, Berkeley as a postdoctoral chemist, and then was appointed as a research scientist at the Lawrence Livermore National Laboratory, Department of Energy, USA, before retuning to Japan in late 2002. He was a lecturer at the Department of Earth and Planetary Science until 2008 and then moved to the Atmosphere and Ocean Research Institute, where he was an associate professor before becoming a full professor. His research interest is to reconstruct past climate and environments to better understand physics and interactions of Earth’s various components such as cryosphere, ocean, atmosphere as well as biosphere.
