[3] After earning her doctorate, Annen joined the University of Bristol, where she worked on models of magma injection and incrementally emplaced intrusions.
[7] Her research combined numerical simulations with heat transfer models to better understand magmatic processes.
[4] She was particularly interested in the genesis of differentiated melts and how pluton emplacement impacts the growth of large magma chambers.
This buoyancy results in less frequent eruptions and is powered by the accumulation of less dense magma underneath volcanoes.
[14] In 2021 Annen joined the Czech Academy of Sciences[2] where she works on the formation and differentiation of magma chambers.
