Matthieu Cartigny

Dr. Matthieu Cartigny is an associate professor at Durham University, UK. Over more than a decade his research has focused on the dynamics of fluid flow and sediment transport over the surface of the Earth. About 10 years ago, a series of papers coming from his PhD thesis (with George Postma as advisor at the University of Utrecht) and a number of subsequent publications brought about a huge improvement in our understanding of the gravity flows, with main emphasis on supercritical flow conditions and the structures it produces in the resulting deposits. Experimental work, using both numerical and physical scaled models, was key to the innovation his work has brought to the field of physical sedimentology. Mathieu Cartigny has used his earlier experience as a hydraulic engineer and naval officer to a great benefit in his research, which currently centres on direct monitoring of turbidity current in the ocean floor. Matthieu’s plenary lecture at the IAS 2021 Meeting of Sedimentology in Prague, entitled “Using novel deep-sea technology to demystify turbidity currents”, will bring us the latest on current progress in this field.
