Research and expertise

I am a civil engineer specialising in geotechnical engineering, acoustic emission (AE) and smart infrastructure. My current research can be categorised into two primary areas: (i) the development of acoustic emission monitoring for geotechnical applications, which spans element testing of fundamental soil behaviour to full-scale experiments with buried infrastructure; and (ii) the investigation of climate change impacts on infrastructure deterioration and performance.

I was the Co-Inventor of the Slope ALARMS and Community Slope SAFE AE landslide early warning systems, which have been commercialised by RST Instruments Ltd (Geo Acoustic Aware). I am the Principal Investigator of an EPSRC Fellowship titled Listening to Infrastructure, which is developing AE sensing technologies for a range of new geotechnical domains (e.g. buried pipelines, foundations, tunnels, retaining structures and dams). I am also a Co-Investigator of the EPSRC Programme Grant, ACHILLES, which is investigating the impacts of climate change on infrastructure earthworks.

I have received numerous prizes for my research and enterprise activities, including the Philip Leverhulme Prize in Engineering, Worshipful Company of Engineers’ Hawley Award for Engineering Innovation, Thomas Telford Premium and Professor Dearman Young Author of the Year Award. I welcome enquires from postgraduates who wish to study for a PhD in my areas of research interest.

Teaching

I contribute to learning and teaching activities across the School’s programmes. This has previously included modules on Mechanics of Materials, Structural Analysis and Mechanics, and Surveying. I currently teach Soil Mechanics and Geotechnical Engineering topics to undergraduate students and supervise research dissertation projects. 

Undergraduate

  • Soil Mechanics and Geotechnical Engineering modules on the civil engineering programmes; and
  • Supervision of dissertations on topics aligned to my research interests

Career

I graduated from Loughborough University in 2012 with a first-class MEng degree in Civil Engineering. I then joined Coffey Geotechnics as a Graduate Geotechnical Engineer, where I was involved in the design and construction monitoring of several projects, before returning to Loughborough University to carry out research in Geotechnical Engineering. I was awarded a PhD in 2015 for a thesis titled “Quantification of slope deformation behaviour using acoustic emission monitoring”. This was followed by an EPSRC Doctoral Prize Fellowship at Loughborough University between 2015 and 2017. I was awarded an EPSRC Postdoctoral Fellowship (Listening to Infrastructure, EP/P012493/1) in 2017 and became a Lecturer (Assistant Professor) in Civil Engineering at Loughborough University, promoted to Senior Lecturer (Associate Professor) in Civil Engineering in 2020.
