Research Overview

My research focusses on the dynamics of geophysical flows, their associated morphologies and the eventual deposits that are left in the rock record. I use field measurements, experiments, numerical models and the sedimentary record to test morphodynamic hypothesis from different perspectives. I am fascinated by the autonomous behaviour observed in these processes and the broad scope of beautiful patterns that they produce.

Currently, my research is mainly focused on direct observations of turbidity currents in settings varying from large submarine canyons to small delta front channels. These observations include the first deep ocean measurements of unprecedented Mississippi-River-size, week-long flows. These flows show a complete new flow structure, where a dense frontal parts of the flow outruns a dilute quasi-steady trailing body. Other datasets include ~100 individual smaller flows occurring in delta channels, which now allow us to constrain for the first time what it takes for a small flow to ignite into a fully develop turbidity current. More generally, I am trying expand on our observation capabilities by bringing in techniques that are new to this field, such as CHIRP systems to image dense basal layers on turbidity currents, electronic resistivity tomography to measure dense basal layer non-intrusively in the laboratory, acoustic inversion techniques to explore sediment concentration within deep-ocean turbidity currents and fully three-dimensional numerical modelling techniques to study the link between supercritical flows and their related bedforms.

In my future research I want to expand my research scope to other geophysical flows. This is currently being reflected in modelling work on sediment waves on submarine flanks of volcanoes to constrain submarine continuation of pyroclastic flows, and by linking sedimentological signatures to morphological seafloor features in a large glacially formed trough on the Antarctic shelf.
