With a keen eye for application, he specialises in the integration of geo-data to guide engineering solutions.
David Rushton

David Rushton

David Rushton has 13 years’ experience in geotechnical engineering, geohazard analysis and geospatial data management. He specialises in clear communication of geotechnical data through in-depth knowledge of soil parameters and the innovative presentation of data to enable effective application to ground engineering problems.​
Sean Pearce

Sean Pearce

Senior Engineering Geoscientist
Sean Pearce is a chartered Geologist with over 6 years’ experience working on site characterisation for onshore and offshore developments. With a background in Engineering Geology and Geoscience, he has worked on desk studies, data acquisition, foundation design and geohazard assessments to solve engineering challenges. He has also contributed to planning applications and provided expert witness services in arbitration proceedings.
Finlay Hannah

Finlay Hannah

Finlay Hannah is a Geophysicist with 3 years’ experience in geoscience data analysis, interpretation and report writing, as well as an MSc in Petroleum Geoscience. He has a background in the offshore site survey industry and experience in shallow geophysical data acquisition in various locations around the world. He specialises in seismic interpretation, geoscience data analysis and marine geohazards.
Kate Oakes

Kate Oakes

Graduate Engineering Geoscientist
Kate Oakes has a background in geoscience, geohazards and structural engineering and is part of the site characterisation team, evaluating onshore and offshore ground conditions. Kate’s background in physical geography gives her a strong appreciation of geomorphological processes and their implications for ground conditions within the development foundation zone.


Mike Fiske

Mike Fiske has more than 30 years’ experience in the offshore industry, with senior-level project management experience in all aspects of geophysical surveying and interpretation. He has led break-through projects for oil-majors, bringing a level of guidance and oversight rarely matched with many demonstrable successes for complex engineering projects.

Richard Brewer

Rich Brewer has 20 years’ offshore experience as survey engineer, survey manager, client representative and consultant for oil, gas, renewables and survey companies. With a NEBOSH qualification in International Health and Safety, he has performed technical audits of survey vessels, planned technical survey operations and consulted on the quality, safety and integrity of survey projects for major clients.

Catherine Villaret

Dr Catherine Villaret has 25 years’ experience in sediment transport and coastal process modelling for harbours, renewables and oil & gas projects. She was part of the TELEMAC development team at EDF and is an expert in the modelling of turbulent flow and sediment interactions. She has developed a number of cutting edge techniques including 3-way coupling, bed roughness prediction, long term simulations and uncertainty analysis. ​

Simon Dykes

Simon Dykes has 40 years’ experience in the management, execution and QC of survey projects ranging from small river and inshore surveys to rig positioning, large offshore geophysical surveys and oilfield developments, many in remote areas. Simon has also worked on large civil engineering projects including the Thames Flood Barrier in London and the Melbourne to Sydney onshore gas pipeline.

Mark Higson

Mark Higson has over 20 years’ experience in offshore site investigation, including survey design, acquisition, data QC and interpretation. Having represented numerous clients globally, he has a track record of matching data acquisition to engineering requirements and keeping a close eye on contractor performance and deliverables.

Dr Mark Lee

Dr Mark Lee is one of the world’s leading engineering geomorphologists and geohazard risk specialists. He has nearly 40 years’ experience in coastal engineering and the oil and gas industry, specialising in quantitative risk assessment, terrain evaluation, landslides and coastal cliff recession. Mark has undertaken pioneering work in geohazard risk assessment and is an expert in communicating, quantifying and mitigating georisks.

Sanjay Shinde

Sanjay is a highly experienced geotechnical engineer and has project managed numerous large-scale and technically complex geotechnical developments. He has worked closely with the EPG directors for over ten years and has a full appreciation of integrated ground models and geohazard assessment. He also has a wealth of experience working in permafrost environments.
