- A multidisciplinary study of the recent sedimentary processes in the Gollum Channel system to the West of Ireland MSc (Ghent University, Belgium)
- High-resolution seafloor evidence for glacial and post-glacial environments in the tidally dominated Irish Sea on the NW European Shelf PhD (University College Cork)
I am Lecturer in Marine Geology and Geophysics. I focus my research on seabed morphodynamics. I study sediment transport and bedform dynamics, more particularly the formation of amplified sediment waves, enhanced sediment mobility around seafloor objects and its link to sustainable management of engineering projects. I also study seabed morphodynamics linked to glacial dynamics, reconstructing the demise of marine-terminating ice streams from investigations of the seafloor, and understanding seabed habitat suitability on exposed seafloor when glaciers have retreated.

I focus my research on seabed sediment mobility:
A. Seabed sediment transport and bedform dynamics:
1. Understanding the role of methane seepage in the formation of amplified sediment waves:
-> 2014-2019: project “Bedload transport of sediment mixtures in shelf seas”, funded by NERC (ENVISION PhD studentship, with CASE partner NOC-L and extra funds from Llanelli Sand Dredging Ltd
-> 2011 onwards: project “AmSedIs”, funded by the European Commission (EUROFLEET) and with experts in biogeochemistry, seabed geomorphologists, sedimentologists, geophysics experts and numerical modellers across Europe.
2. Understanding enhanced sediment mobility around seafloor objects:
-> 2018-2022: project “Seabed integrity around objects in a complex marine environment”, funded by KESSII (PhD studentship) and via multi-disciplinary collaboration with experts in marine geo-archaeology, Computational Fluid Dynamics and sediment transport modelling.
-> 2016-2018: project “Unstable shipwreck sites in sand & gravel”, funded via a Returning Fellowship by Welsh Government: Sêr Cymru National Research Network for Low Carbon, Energy and Environment (NRN-LCEE)
-> 2015: project “WWI Shipwrecks in the Irish Sea”, with shiptime funded by the Marine Institute, Ireland
3. Seabed dynamics and its link to sustainable management of engineering projects:
via collaboration with renewable energy developers and with links to iCRAG (Ireland’s national geoscience research centre supported by Science Foundation Ireland).
B. Seabed morphodynamics linked to glacial dynamics:
1. Understanding the demise of marine-terminating ice streams from investigations of the seafloor:
-> 2015-2019: project “Glacial sculpting and post-glacial drowning of the Celtic Sea”, funded by NERC (ENVISION PhD studentship)
-> 2012-2018: Consortium project “BRITICE-CHRONO”, NERC-funded and with experts in glacial geomorphology, geochronology, palao-oceanography and ice sheet modelling
-> Ongoing: object-oriented modelling for glacial landscape recognition, in collaboration with modellers in India.
2. Understanding seabed habitat suitability on exposed seafloor when glaciers have retreated:
-> 2017-2020: project “Impacts of deglaciation on benthic marine ecosystems in Antarctica (ICEBERGS)”, NERC funded (CONICYT - NERC Antarctic programme), in collaboration with experts in benthic ecology, palaeo-oceanography, glacial dynamics and sclerochronology.
-> 2014: project “The collapse of the Irish Ice Sheet in the Celtic Sea sector and its marine habitat legacy”, with shiptime funded by the Marine Institute, Ireland
