I use computer experiments to investigate a range of topics spanning from sedimentary structures at Earth's surface to subducted slabs in the upper mantle. My research addresses for example the formation and evolution of continental rifted margins, microcontinent formation, subduction, continental collision, numerical code development, and analogue-numerical model comparisons.

I use structural geology and thermchronology, trying to understand the rock deformation and orogenesis. Recently, I study Phanerozoic compressional and extensional tectonics in South China, Cenozoic intracontinental orogeny and subduction-collision systems in Iran, Neotethys subduction and collision in Turkey, and mountain building in the Himalayas.

The focus of my work is the development of numerical models of the Earth's interior that can help us understand how the Earth's surface has developed. In particular, I investigate mantle plumes, answering questions like: How do mantle plumes form, how do they entrain chemically heterogeneous material, and how is this process influenced by global mantle convection patterns? How do plumes rise and how much dense material can they carry? And how do plumes interact with the lithosphere when they approach the surface, how is melt generated in rising plumes and where and how fast does this melt migrate upwards? In addition, I also work on other two-phase flow problems in magma dynamics, and I am interested in grain size evolution in the Earth's mantle and its influence on rheology. I am one of the maintainers of the free modeling software ASPECT (Advanced Solver for Problems in Earth's Convection, https://aspect.geodynamics.org/). ASPECT uses modern numerical methods to support research in simulating convection in the Earth's mantle and elsewhere.

Virginie Pinel received the Ph.D. degree in geophysics from the Institut de Physique du Globe de Paris, Paris, France, in 2002. She was a Postdoctoral Fellow supported by the Centre National d’Etudes Spatiales. Since 2004, she has been a Researcher with the Institut de Recherche pour le Développement (IRD). Her main research interests include SAR data application to volcanoes study as well as magma storage and transport modeling. She pioneered the understanding that surface loads have a critical influence on the stability of magma chambers and the movement of magma. She is an expert on crustal deformation at volcanoes and of analytical and Finite Element Modelling of volcanic processes. She recently started applying sequential data assimilation to volcano geodesy.

Patrice Rey was born in France on the same day Bob Dylan delivered "Blowin' in the Wind" to the world. He (Patrice, not Bob) has built an International career through his involvement with no less than 12 Universities and Research Institutions across three continents. He is bridging structural geology, tectonics and geodynamics through a blend of field-based and computer-based research. He is interested in tectonics over the 4.54 Gyr of the Earth's history.

I am a University Professor in Germany, and have perviously held a faculty position at the University of Otago in New Zealand (as Lecturer, Senior Lecturer, and Associate Professor) since 2009. As a Professor of Structural Geology and Tectonics, I study localisation in faults and shear zones throughout Earth’s lithosphere; rheology of geological materials; SW Pacific tectonic plate motions; paleoseismology and landscape evolution, and geo-resource sustainability. Methods: I make field observations, undertake microtextural analysis, particularly by electron beam, and synchrotron methods, perform deformation experiments, and validate results by computational models. I lead and participate in scientific drilling projects, and co-ordinate drilling consortia membership and scientific directions.
