While our team's core expertise is in numerical modeling, data
collection, be it in the field or the laboratory, is of course crucial
for our understanding of planetary dynamics. We conduct passive
seismology experiments and collaborate with a range of geologists,
geodesists, and geochemists to this end, and are involved in a number
of multi-disciplinary experiments across the globe. I believe that
some experimental and field experience is important even for
theoretical geophysicists.
Northern Chile Collaborative Seismic Experiment (2023 - 2025)
A collaborative project between the National University and Catolica
in Santiago, Chile, GFZ, and UTIG.

A five-year, collaborative, NSF funded effort to
advance integrative modeling capabilties within the
megathrust context with focus on the regional settings of
the Japan system, New Zealand, and Cascadia. Read more on the
MTMOD web

A field trip run by University of Potsdam (Manfred Strecker) and
Universita di Roma TRE to study paleoclimate and tectonics of
the Kenya rift.

We studied the Banda Arc (PI: Miller, co-PIs: West and Becker)
and how continental collision and subduction are expressed
tectonically and in terms of topography.

Sculpting the Earth's
topography: insights from modelling deep-surface processes
(TopoMod, 2012 - 2014)
We were involved in the ESF TopoMod project led by Universita
di Roma TRE and involving U Amsterdam, GFZ, ETH Zurich, U Durham, U
Rennes, ICTJA-CSIC, U Florence, and U Parma. The role of mantle
convection in shaping Earth's topography is explored using geology,
seismology, and geodynamics. TOPOMOD was an EU ITR training project
designed for a team of early-stage and experienced researchers to
investigate and model the origin and evolution of topography of the
continents over a wide range of spatial and temporal scales.
