+<h3>What We Need to Model Planetary Interiors: The Role of Research Software in Computational Geodynamics</h3>
+Speaker: Rene Gassmoeller<br>
+GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany<br><br>
+
+Abstract:
+<p>
+Geodynamics - understanding the internal dynamics of the Earth and
+other planets - depends heavily on the use of numerical algorithms and
+their software implementations to make sense of the data we collect
+and to understand our exposure to geohazards and the availability of
+georesources. The software we use to understand these processes varies
+from solvers for wave propagation and elastic deformation over
+reactive multi-phase flow models and magneto-hydro-dynamics to
+micro-scale mineral physics processes and ab initio material property
+prediction. As varied as the software is typically their development
+history, and with the advent of modern standards for research software
+the geodynamics community decided in 2005 to establish an organization
+dedicated to improving software standards - the Computational
+Infrastructure for Geodynamics, CIG. 20 years later I will discuss the
+role that CIG has played in supporting research software in the field
+of computational geodynamics, and the lessons we learned. I will also
+present application cases of CIG software, with a particular focus on
+the ASPECT software - the Advanced Solver for Planetary Evolution,
+Convection, and Tectonics - and how it helps us to understand
+deformation processes in Earth's interior, such as the movement of
+tectonic plates, and the influence of mineral phase transitions on
+Earth's long-term evolution.

+Bio:
+<p>
+Rene Gassmoeller is a staff scientist at the GEOMAR Helmholtz
+Centre for Ocean Research Kiel, and previously was the technical lead
+for the NSF-funded community organization Computational Infrastructure
+for Geodynamics. He completed his PhD at the German Research Centre
+for Geosciences (GFZ) in Potsdam, Germany and did postdoctoral work at
+Texas A&amp;M University, Colorado State University and the University of
+California, Davis as well as an appointment as visiting assistant
+professor and research scientist at the University of Florida. His
+research interests lie in computational geodynamics, numerical
+mathematics, and software engineering, with a particular focus on
+processes in the deep Earth and developing the software we need to
+understand them.
