Research interests

My primary research is focused upon the recognition of the role of material deformation characteristics in controlling the spatial and temporal nature of rockfalls and landslides. Using data collected both in the laboratory and in the field, I am interested in exploring theoretical models which underpin recent developments in the understanding the mechanics of slope failure. My research is most often end-user focussed, with an emphasis on risk management which broadly considers when, why, where and how landslides occur. My recent research has focussed in two areas: earthquake-triggered landsliding; and, the development and use of 3D time-series terrestrial imaging techniques to monitor slope failure at unprecedented levels of spatial and temporal detail.

I am currently PI on series of projects that enable my research group to pursue these interests. For example, I lead the long term Coastal Behaviour and Rates of Activity (COBRA) research collaboration that runs in partnership with ICL Fertilizers (UK) Ltd, conducting fundamental research on rock slope failure, coastal evolution and deep mining in North Yorkshire, UK. I also lead a project focussed around providing a rolling assessment of the evolution of landslide risk in the area impacted by the 2015 Nepal earthquakes, working with DFID-Nepal and the National Society for Earthquake Technology (Kathmandu).
