My research interests relate to the overarching theme of glacier-climate interactions, with particular focus on glacier response to rapid climate change. This theme is explored through research on glacial geomorphological and sedimentological records at a range of spatial (corrie to plateau ice-cap) and temporal (Last Glacial-Interglacial Transition to recent) scales. A fundamental principle of my research is to integrate GIS, remote-sensing and field methods in a multi-method approach, including the use of innovative approaches (e.g. Structure-from-Motion photogrammetry). Furthermore, my research employs a process-form approach, emphasising the importance of both the surface form and internal composition of glacial landforms, and draws on modern process analogues to inform understanding of past glacial processes. Specific research interests include:
- Pattern, dynamics and timing of Quaternary glaciations
- Changes in Icelandic outlet glacier dynamics in response to climate change
- Formation, significance and preservation potential of moraines
- Geomorphological signature and dynamics of plateau icefields
Pattern, dynamics and timing of glaciation on the Gaick, Central Grampian Highlands, Scotland
Despite recent advances in the understanding of Quaternary glacial events in Upland Britain, particularly relating to the Loch Lomond Stadial (broadly correlated with the Younger Dryas; c. 12.9–11.7 ka), there remain large areas in Scotland where the pattern, dynamics and timing of Quaternary glacier fluctuations are poorly understood. This is exemplified by the Gaick, Central Grampian Highlands, where widely differing interpretations of the sediment-landform archive have been postulated. Elucidating the pattern and timing of glacial events in this region is of key importance as it has significant implications for the understanding of palaeoclimate during the Last Glacial-Interglacial Transition (16–8 ka). This project seeks to resolve these issues through the application of a combination of geomorphological, sedimentological and geochronological methods.
Modelling plateau icefield stability under warming climate scenarios

This project aims to use the glacial geological record left by the Little Ice Age (LIA) expansion of Svartisen Østre Icefield, Norway, to investigate past, present and future icefield behaviour over decadal to centennial timescales. I was a member of the field team that undertook geomorphological mapping and sedimentological investigations in August 2016.
