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.
My particular expertise is as a marine geoscientist, with extensive knowledge and experience of: sediment core analysis, side scan sonar, 2-D seismics, video data and GIS.
I am also employed as a Senior Projects Geophysicist at Cathie Associates, an offshore geotechnical and geophysical consultancy.
September 2013 to present
Visiting researcher at the UCL Department of Geography and Senior Projects Geophysicist at Cathie Associates.
During this period my research has focused on natural hazard risk and I have been working commercially with a number of offshore UK wind farm developments in the North Sea. One of my aims is to develop links between academia and industry to strengthen risk analysis for offshore renewables.
May 2006 to September 2013
Part-time PhD at UCL department of Geography investigating the relationships between submarine mass movements and climate change.
During this period I also founded my company, MAJO Consulting ltd, and have worked offshore UK, Norway, Ireland, Germany, France and Congo as a marine geophysicist working on a number of projects including offshore wind farms, cable and pipeline surveys.
October 2000 to April 2006
This period covers a break from academia, when I worked at the specialist cheesemongers Neal's Yard Dairy.
Over the years my roles included:
Retail department manager, responsible for ~30 staff and a annual turnover of £1.5 million
Project manager, in which role I organised the relocation of the wholesale department and the construction of a new shop.

Submarine mass movements
My PhD focused on slope failure on the Barra Fan, NW British continental margin.
This work employed a broad range of methods, including sediment core analysis (sedimentology and geochemistry), 2-D seismics, bathymetry and side scan sonar. Using these data I refined the shallow stratigraphic model of the Barra Fan and mapped the sedimentological processes using GIS methods. This has allowed me to understand the environment in both local and regional contexts.
The major findings from my doctoral work concern the timing of Peach 4, the most recent large slope failure, to between 11 and 12 ka cal BP; and the role of bathymetry and ocean circulation interacting at different water depths to influence sediment deposition and erosion on the fan. This latter process is likely to vary significantly between glacial and interglacial periods, enhancing permeability contrasts between clays and silts: increasing the potential for high pore water pressure reducing the strength of the sedimentary column.
Sub-Antarctic marine geology
A participant in BAS research cruise JR206, to the Scotia Sea and South Sandwich volcanic arc I have been working with colleagues to improve our understanding of the region's geological evolution.
Of particular interest to me is the role of transpression on the southern continental margin of the South Georgia micro-continent and the presence of contrasting mass transport deposits to the south of this margin. Work in the South Sandwich is focusing on the morphology of the arc's large sediment wave fields, how these evolved and why there are so few slope failures in this region.
I study a range of geohazards, from submarine landslides, to tsunamis, tropical and extra-tropical cyclones.
This work has been undertaken in collaboration with the reinsurance industry and is now looking at the affect of increasing exposure on levels of risk. Such changes have the consequence of changing impact magnitude, where previously an event may have caused minor damage, an event of comparable physical magnitude may now cause more significant damage simply due to the higher exposure.
Recently I have begun to investigate methods of assessing hazard - structure interaction and mapping submarine landslide susceptibility.
In addition, and intrinsically related, to the above I am strongly interested in the study of past (and by inference future) climate. In particular I have conducted significant research into gas hydrates and their potential role in influencing climate. Recently I have also been collaborating on a study looking at the influence of bathymetric changes on ocean circulation during the Pliocene.
Fellow of the Geological Society
Member of the Quaternary Research Association
Member of the International Association of Sedimentologists
I have worked on a number of projects with the reinsurance industry, with companies including AON and JLT Towers Re.
I was heavily involved in a multi-departmental UCL climate change workshop for AON's UK board, during which I presented a talk on risks associated with oil and gas production in the Arctic.
Projects with JLT Towers Re have been more substantial. One assessed the risks from tsunamis to international airports and another conducted hazard scenarios for extreme weather and seismic events on North Sea oil and gas infrastructure.
The tsunami work attracted considerable media coverage (click source for link):
EU consultation on seabed mining
With significant consulting experience for seabed aggregate extraction I contributed towards the UK NOC Association response to the recent EU consultation on seabed mining.
The NOC Association response may be downloaded here.
ClimateSnack is an international organisation, which aims to improve early career researchers' communication skills. Based around a blog format, it works by researchers writing articles, which they then read aloud to the local group. The group then offers critique via discussion, before the author edits and posts online. I have helped form and run the UCL group, which is growing and represents a broad church of climate researchers.
This is a model for writing improvement that I highly recommend.

2012 - Contributor at a workshop for UCL Geography department GIS Masters course.
2011 - Lecturer for the UCL Geography department MSc in Climate Change. Wrote and presented lectures on cyclones (physical processes and hazard) and tsunamis (causes, propagation and inundation).
2009 to 2007 - Tutor to undergraduates. Provided support and advice to students, with a considerable amount of assessment, including marking of essays and presentations.
