I am a visiting researcher in the UCL department of Geography, having completed my PhD thesis (investigating the morphology and timing of submarine mass movement on the northwest British continental margin) in 2013. I also work as a marine geoscientist (I have expertise in Side scan sonar, 2-D seismics, video data, GIS and CAD).
Additionally, over the last few years I have been conducting work into geohazard (including tsunami, earthquake, submarine slope failure and storm) risks for the reinsurance industry, with projects investigating risk to airports and offshore infrastructure.

My PhD focused on the relationships between submarine mass movements and climate change. The majority of my work was centred on the Peach debrites within the Barra Fan (NW British continental margin).
The PhD employed a wide range of techniques including high-frequency 2D seismics, multibeam-bathymetry, sedimentology and planktonic foraminiferal stable isotope geochemistry.
Using the geophysical methods I constructed a GIS based 3D model of the Peach debrite region within the Barra Fan, through the analysis and interpretation of which I gained a better understanding of the dynamics and morphology of the most recent sediment failures.
Sediment core analysis was used to place the event within its correct climatic and environmental context. Methods employed included: particle size analysis; bulk sediment XRF geochemistry, and planktonic foraminiferal stable oxygen and carbon isotopes. We used AMS 14C dating to date pelagic sediments overlying the slumped deposits.
Additional research interests:
- Sources, and the role, of methane in Quaternary climate change: attempting to untangle the role played by various sources.
- Natural hazard and structure interaction: focusing on offshore infrastructure.
- Tsunami generation and impact: roles of submarine mass movements in generating tsunamis. Some work I undertook for the reinsurance firm JLTRe was reported on in the
- Potential impact of future climate change: methods of reducing and mitigating. I am an author of the UCL Environment Institute's Audit of UK Greenhouse Gas emissions to 2020: will current government policies achieve significant reductions? which formed the basis of Channel 4's 'Greenwash' dispatches episode.
- Development of scientific method and epistemology with modern western philosophy.
- In 2005 I participated in the RRS Charles Darwin cruise 174 with the . This involved swath mapping of the Rockall trough and seismic surveys of the Barra Fan.
- January - March 2010 I participated in cruise JR206 aboard the RRS James Clark Ross. During this cruise we successfully surveyed the southern South Georgia margin and the South Sandwich Island arc.
I have given talks at the following international conferences:
- Climate Forcing of Geological and Geomorphological Hazards (London, 2009). Talk entitled "Is it possible to test whether submarine mass movements and methane hydrates have played a role in late Pleistocene climate change?"
- 4th International Symposium of Submarine Mass Movements and Their Consequences (Austin, 2009). Talk entitled "Investigations on the Peach 4 Debrite, a late Pleistocene Mass Movement on the Northwest British Continental Margin."
- 11th International Symposium of Antarctic Earth Sciences (Edinburgh, 2011). Talk entitled "Active Faulting, Transpression and Sedimentation in Endurance Basin, South Georgia: Potential Use of a Glaciated Continental Margin Basin in Reconstruction of Climatic Variations in the Sub-Antarctic Region."
In addition to which I have given talks at a number of workshops and presented posters at several other meetings.
Since 2007 I have undertaking a variety of teaching roles in the UCL Geography department:
- 2007 - Tutor to affiliate undergraduates. A role that primarily involved giving advice and assisting external students with the more difficult concepts.
- 2008 - Tutor to second year undergraduates. A role that, in addition to providing support and advice to students, required a considerable amount of assessment and marking.
- 2011 - Lecturer for the UCL Geography department MSc in Climate Change. Lectures on cyclones (physical processes and hazard) and tsunamis (causes, propagation and inundation).
- 2012 - Contributor at a workshop for UCL Geography department GIS Masters course. Presented a methodology for using weighted overlays to assess regional submarine slope failure risk.
