Biography

Tobias Keller completed his BSc in Earth Sciences (2003-2006) and MSc in Geophysics (2007-2009) at ETH Zurich where he continued to defend his PhD thesis on numerical modelling of magma ascent ant emplacement in 2013. The following six years were spent with two placements as postdoctoral research associate at the University of Oxford (2013-2016) and Stanford University (2016-2019). 

In 2019, Dr. Tobias Keller took up a position as Lecturer in Computational Geosciences at the University of Glasgow. There he started the Magma Matters Research Lab, a small group of researchers leveraging computational modelling and machine learning tools to study magmatic and volcanic processes on Earth and other planetary bodies.

After spending the years 2021-2023 working as a senior scientist at ETH Zurich while retaining an Affiliate Lectureship at the University of Glasgow, Dr. Tobias Keller returned to the University of Glasgow full time as Reader in Computational Geosciences in 2024.

In 2020, Dr. Tobias Keller received the Division Outstanding Early Career Scientist Award from the Geodynamics Division of the European Geosciences Union for his "multidisciplinary frontier research on some of the most challenging problems related to the generation, transport, and emplacement of magmas using the tools of numerical modelling".

Research interests

Dr. Tobias Keller is a Computational Geoscientist interested in volcanoes and their deep magmatic roots. His research programme spans the role of magmatism in planetary formation and evolution, igneous rock formation in the crust and lithosphere, and volcanism and related hydrothermal and ore genesis processes. His primary research tools include custom-built computational models of multi-phase reactive transport complemented by machine learning relating model outcomes to observational and experimental evidence from geochemistry and petrology, geology and geophysics, volcano monitoring, and resource exploration.
