With a master's degree in Engineering Geology from Imperial College and over 15 years' experience in geotechnical and geo-environmental investigation and consultancy, Matthew has been involved with numerous ground investigations for a wide variety of developments in a range of geological conditions. In 2012, he obtained chartered status from the Geological Society of London, reflecting his level of experience and understanding of geological materials.

Matthew specialises in complex ground investigations and ground movement assessments. He has experience of self-boring pressure meter testing to measure the in-situ stiffness and strength of the London Clay and is familiar with CPT investigations both for strength data and clearance of unexploded ordnance, most recently the use of low-headroom equipment to complete combined CPT and pressure meter testing within a basement car park. Matthew has completed numerous specialist geotechnical analyses, including analysis of an unstable slope on a historical landslip in Hythe, Kent and an analysis of the effects of disused military tunnels on a new development in Chatham.

Matthew completed a four-month placement with the design team of Cementation Skanska in 2017, where he gained valuable experience in the design and analysis of piled foundations and retaining walls. He is a member of our Ground Movement Assessment Group, and has completed numerous detailed ground movement analyses, including settlement predictions for a pile group supporting a high-rise structure near Elephant and Castle and more recently for several deep basements in Central and West London

He is also a member of the AGS Geotechnical Working Group and is presently involved with the recently established Underpinning Focus Group, which is working with the University of Portsmouth to better understand the ground movements associated with underpinned basements.
