The Geodynamics (GD) Division of the European Geosciences Union (EGU) coordinates the scientific programme and related activities on all aspects of geodynamic processes in the lithosphere, mantle, and core. The division also promotes scientific interchange and dissemination of activities carried out by its members.

This blog serves as a platform for the geodynamics community to share news, articles and events. In our Wednesday blog posts, we have several regular features, such as the Geodynamics 101 series, which serves to show the diversity of topics and methods in the geodynamics community in an understandable manner for every geodynamicist and science-fan. We also have Wit & Wisdom posts full of wit (but rarely wisdom). Interesting regional and global geodynamics are discussed in the Remarkable Regions and Peculiar Planets series. The latest geodynamics news can be found in our News & Views posts. On Friday, we have a weekly column called Ask the Sassy Scientist, where an anonymous scientist (who is sassy) answers questions from our readers. If you would like to contribute to the blog as a guest writer, don’t hesitate to contact us!

The Geodynamics Division hopes to address a wide range of topics, as well as the major challenges related to geodynamics. The division publishes updates on Facebook and Twitter

The Blog Team

Iris van Zelst
Iris is a postdoctoral fellow at the University of Leeds in the United Kingdom. Her current research revolves around the geodynamic modelling of subducting plates and intermediate-depth seismicity. Her recently completely PhD was on modelling tsunamigenic earthquakes using a range of interdisciplinary modelling approaches, such as geodynamic, dynamic rupture, and tsunami modelling. Iris is editor-in-chief of the GD blog team. You can reach her via e-mail.


Menno Fraters
Menno is a postdoctoral fellow at UC Davis in the USA. He investiages the interplay between the crust and the mantle through numerical modelling, with a focus on the study of subduction zones. Menno is part of the GD blog team as an editor. You can reach Menno via e-mail.



Anne Glerum
Anne is a postdoctoral fellow in the Geodynamic Modelling section at GFZ Potsdam. Through numerical modeling, she investigates continental rift dynamics, focusing on the effect of along-rift variations as well as magma-tectonic feedback processes on rift evolution. Anne is part of the GD blog team as an editor. You can reach her via e-mail.



Anna Gülcher
Anna is a PhD student in the Geophysical Fluid Dynamics group at ETH Zürich. Her research focusses on (but is not restricted to) the composition and dynamics of the deep Earth, and its control on our planet’s evolution. She aims at integrating her numerical modelling results with geochemical, seismological and geological data. Anna is part of the GD blog team as an editor and is also the ECS representative for the geodynamics division. You can reach Anna via e-mail and she tweets at @AnnaGeosc.


Jyotirmoy Paul
Jyotirmoy is a PhD student at the Indian Institute of Science (IISc), Bangalore. His research work focuses mainly on understanding the evolution of cratons using time-dependent mantle convection models. Jyotirmoy is part of the GD blog team as an editor. He is also manages the GD Facebook page as part of the social media team. You can reach Jyotirmoy via e-mail.


Lucía Pérez Díaz
Lucía is a technical specialist in geodynamics at Halliburton, UK, and an associate researcher at the University of Oxford. Her current research revolves around understanding the feedbacks between mantle activity, plate-scale processes and surface observations and developing improved quantitative plate modelling techniques. She is part of the GD blog team as editor. You can reach Lucía by e-mail or by tweeting @DrPerezDiaz.


Tobias Rolf
Tobias is a researcher at the Center for Earth Evolution and Dynamics (CEED) at the University of Oslo and currently a guest researcher at the University of Münster. Tobias works on planetary-scale geodynamics with a focus on numerical modelling of mantle convection and its surface expressions on Earth and other terrestrial bodies. Tobias is part of the GD blog team as an editor and can be reached via e-mail.



Antoine Rozel
Antoine is a senior researcher at ETH Zürich. Particularly interested in rheology and crust formation, Antoine investigates the evolution of icy and rocky bodies in the solar system. Comparative planetology is a great opportunity to work with applied mathematicians, planetary physicists, geologists, petrologists and geochemists! You can reach Antoine via e-mail.



Grace Shephard
Grace is a researcher at the Centre for Earth Evolution and Dynamics (CEED) at the University of Oslo, Norway. She works on linking plate tectonic reconstructions and mantle structure, especially in the Arctic and Pacific regions. Grace is part of the GD blog team as an editor and part of the social media team for GD Twitter. You can reach her via e-mail.


The Sassy Scientist
The Sassy Scientist is sassy and – surprisingly – a scientist. The Sassy Scientist is a mystery: an integral part of the geodynamics community and at the receiving end of stories on research and scientific experiences from research departments all over the world. With an unprecedented knowledge on all aspects of geodynamics and related topics, The Sassy Scientist can answer any question. Patiently waiting for you to submit yours here


The Social Media Team

To promote the activities of the EGU Geodynamics division, the social media team manages the EGU GD Facebook and Twitter accounts. The social media team currently consists of Jyotirmoy Paul and Grace Shephard, who are also part of the blog team, and Charitra Jain and Antoniette Greta Grima.

Antoniette Greta Grima
Antoniette is a postdoctoral fellow at UT Austin, Texas (US). She is interested in subduction dynamics and her work focuses on the dynamics of deep slabs and their interactions with the surface topography. Antoniette is part of the social media team for GD Twitter. You can reach Antoniette via e-mail and she tweets at @Geoniette.


Charitra Jain
Charitra is a postdoctoral researcher at the Department of Earth Sciences at Durham University, United Kingdom. He investigates the formation of continents (crust and the underlying cratonic lithosphere) using mantle convection models. Charitra is part of the social media team for GD Twitter. You can reach him via e-mail.
