Research interests:

My research expertise lies in the areas of Holocene sea-level change, coastal and climate change, tsunami sedimentation and diatom biostratigraphy. Present research activities include projects on Holocene relative sea level changes and tsunamis in the Maldives archipelago, Sweden, Scotland and Greenland. In Scotland, ongoing projects include the reconstruction of former sea level changes and extreme flooding events on the Isle of Skye and the Orkney Isles. In addition to research interests on a Holocene timescale, I am working on recent environmental changes with a study on the sedimentology and geomorphology of recent storm deposits in the Outer Hebrides as well as a study looking at changing sedimentation patterns and hydrodynamics in estuaries on the west coast of the Outer Hebrides. A study of tsunami sedimentation in the Maldives as a result of the 2004 Indian Ocean Tsunami is also a key theme.

Current Research Interests

-Holocene relative sea level changes in Scotland (peripheral islands), Greenland, Sweden, Maldives

-Coastal and climate changes in Scotland (Outer Hebrides, N Scotland, Northern Isles)

-Relative sea level change, coastal evolution and coastal archaeology in Scottish islands

-Diatom biostratigraphy and sedimentology of tsunami and storm deposits (modern, historical and pre-historic events)

-Modern estuarine hydrodynamics (Outer Hebrides) using 210Pb and 137Cs to determine sedimentation rates

Active research projects:

Assessing the risk to the coastal and rural road network in Scotland due to the effects of storms and extreme rainfall events (January 2016 – June 2016)

The first inter-new-school grant between Geography (Sue Dawson) and Civil Engineering (Mike Brown, Jonathan Knappett) together with TRL (Transport research Laboratory) and Transport Scotland, the project with a 4-mmont PDRA, will use existing research data to develop a robust risk management tool, easily utilized by asset managers to tool that can be used by industry to examine rural road transport assets in Scotland that are likely to be at risk from the effects of extreme rainfall and storms and differing future climate change scenarios.

Will climate change alter the landslide-tsunami risk to the UK? (January 2012 – December 2017)

The Landslide-Tsunami Project is a consortium project and part of the NERC Arctic Research Programme. The aim is to assess whether climate change in the Arctic will increase the risk of landslide-generated tsunami to the UK.
