When reading a scientific paper or a text explaining the physical workings of the Earth, one of the most striking aspects is the methodological approach—sometimes involving numerical models, other times fieldwork and/or rock geochemistry. This diversity of approaches can initially cause some discomfort, a feeling that things are like square pegs in round holes. How …[Read More]

How do rocks fail and flow: A beginners guide to rock rheology
The field of rock rheology may seem a bit ‘odd’ at first glance to those geoscientists who are vaguely familiarized with the topic of geodynamics. Often, rocks are considered massive and competent geomaterials that display a sudden (and sometimes violent) brittle failure (earthquake alert!). However, when considering the high temperatures and large timescale characteristics of …[Read More]
Applying for a PhD in Geoscience: To do or not to do
Fresh out of your bachelor’s degree, or more commonly these days, your master’s degree, it can be tempting to pursue your PhD as quickly as possible. While there are compelling reasons to dive straight in, rushing into a PhD might not be your best choice. To be or not to be a researcher? Before …[Read More]
Phase transitions control plume layering during Earth’s secular cooling
Earth’s structure and dynamics have evolved quite a lot since its formation, and so has mantle dynamics and convection patterns changed along with it. It turns out that phase transition in certain mantle minerals can be an important driver of this change. Today, Ranpeng Li from GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany …[Read More]
One Ring to Rule Them All: The Geology of Middle-earth
Few fantasy worlds have captured the imagination of readers and viewers like J.R.R. Tolkien’s Middle-earth. Whether you first encountered it through The Lord of the Rings or the sweeping visuals of Peter Jackson’s films, chances are your eyes lingered on the same thing geologists can’t help obsessing over: the mountains. Towering, treacherous, mysterious — the …[Read More]
Resisting self-guilt as a PhD student
Self-guilt is a common feeling among PhD students. It often leads us to devalue ourselves more harshly than is fair and to form unrealistic expectations. It is important to understand how it shows up in our daily work, what fuels it, and how we can resist it — because over time, it can quietly undermine …[Read More]
Reflecting on the 2025 Gordon Research Seminar (GRS) – Interior of the Earth
This week in News & Views, Heidi Krauss, a PhD student at Michigan State University, shares her experience co-chairing the 2025 Interior of the Earth Gordon Research Seminar, held at Mount Holyoke College in South Hadley, Massachusetts. Earlier this year, I had the opportunity to help co-chair the Gordon Research Seminar (GRS) on the Interior …[Read More]
Simulating the Deep Earth with MAGEMin: A Toolkit for Thermodynamic Modeling in Geodynamics
Understanding how rocks melt, deform, and evolve within Earth’s interior is a central challenge in geoscience. These processes span a wide range of spatial and temporal scales and are governed by complex interactions between temperature, pressure, composition, and phase stability. Capturing this complexity in numerical models requires integrating mineral thermodynamics directly into geodynamic modeling frameworks. MAGEMin …[Read More]
Unraveling volcanic patterns between adjacent rift zones
Continental rifts are a prime example of how the forces at work beneath our feet are constantly shaping our world, and often host volcanic activity. The patterns and distribution of volcanism in rift settings, however, is far from intuitive. The picture gets even more complicated if we look between the segments that often make up …[Read More]
Don’t Stop Me Now: A Fracture Mechanics Perspective on Earthquake Nucleation
How do earthquakes start? Earthquakes occur when a block of rock rapidly slides past another along an interface or a discontinuity in the medium and release energy in the form of seismic waves. Turns out, the surface of the earth is riddled with a lot of these discontinuities, which we call “faults”. If we plot …[Read More]
