Research Interests

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.
