Research interests

My research is primarily in the area of coastal geomorphology, management and coastal responses to climate change. Understanding how contemporary processes operate to form rock coasts continues to be a key area of research. Recent work has focused on the impact of the Kaikōura 2016 earthquake on rock coast morphology and processes. This work is now supported with a Marsden Fund grant (2019-2021). Ongoing interests are in how geological setting influences morphology, erosion rates and processes on rock coasts. This has been a collaborative project with Dr Larissa Naylor (University of Glasgow), working on the Glamorgan coast of south Wales, UK. An extension of that work includes understanding the impact of storms on rock coasts and in particular the erosion and transport of boulders. More recent research in the area of coral reef geomorphology and response to climate change has included work in the Maldives and Mexico.

I have a broader interests in contemporary processes causing the development of coastlines. Other research has included rip currents, beach morphodynamics in fetch limited environments and rock weathering in coastal environments. I have worked collaboratively in China where I was involved in a project examining shoreline response to typhoon with Professor Zhongyuan Chen of East China Normal University. Further research and consultancy work has included the investigation of shoreline processes on lakes and lacustrine management. I acted as a scientific advisory to the then Murray-Darling Basin Commission and for 9 years monitored shoreline response to lake operations at Lake Victoria (NSW).

My interests in coastal management includes erosion and hazard mitigation and conservation of coastal environments. I regularly provide coastal management advice to communities, councils and government. Consulting usually takes the form of hazard assessment, expert witness in planning tribunals, technical reviews, and environmental impact assessments.

I am also a member of the Coastal People: Southern Skies collaboration that connects communities with world-leading, cross-discipline research to rebuild coastal ecosystems.

Potential student projects

I am happy to supervise any student with an interest in coastal geomorphology, coastal processes, management and hazards. Possible topics include (not exclusively):

  • Impact of Kaikoura earthquake on coastal morphology
  • The value of rock coasts, an ecosystem services approach
  • Relative role of waves and weathering on shore platforms
  • Assessing erosion rates on rock coasts with a multiple scale approach (from microns to metres)
  • Rock weathering in coastal and terrestrial environments using field and laboratory approaches
  • Beach morphodynamics particularly in fetch limited environments (lakes and estuaries)
  • Morphodynamics of mixed sediment beaches
  • Geological control of rock coast evolution
  • Boulder transport by storm waves and tsunami
  • Testing the vulnerability of rock coasts to climate change, challenging assumptions about low vulnerability
