Geomorphology is my main thing & much of my work draws upon cosmo & numerical modelling to quantify rates of erosion, transport & deposition in sedimentary environments. The key themes are as follows:
✦ Cold landscapes
Glacial & postglacial processes in high mountain & high latitude environments, including deglaciation chronology, cryogenic soil processes, glacioisostasy & fluvial-glacial interactions. This work has focused mainly on the North Atlantic continental margins.

| Glacially eroded plateau surfaces above 1400m, Jotunheimen, S-Norway. |
✦ River processes & dynamics
Rivers & the evolution of landscapes, including bedrock incision, sediment transport-deposition & the role of channel vegetation in river behaviour. My research began with fluvial geomorphology & rivers remain a core interest. |
Wet Season river surveying & bedload gauging in Magela Ck, N-Australia. |
✦ Extreme geological events
Processes & products of rare, high-magnitude floods triggered by extreme rainfall or collapse of ice-dammed lakes. Understanding the magnitude & frequency of events that shape Earth's surface is central to geomorphology.

✦ Desert environments
Erosion & sediment transport processes in drylands & palaeoenvironmental reconstruction via river, lake & dune proxies. I like dry stony places.

✦ Archaeology
After first touching on archaeology during my PhD studies in central Australia, more recently I have applied luminescence and cosmo burial dating to sites of early human dispersal in Europe, Siberia, and the Levant.
