About Marnie

My career has maintained a balance between active science research and the interface with management, with the aim of translating science into effective policy and determining how policy directs science. To achieve this, my research interests focus on elucidating human impacts on marine and coastal environments, creating solutions to environmental problems by developing remediation and management options. This extends to all aspects of the process, including identifying risks, determining how impacts occur in space and time, measuring, and mitigating impacts. Specifically, my research focuses on fields of biosecurity, risk, marine debris, marine ecosystem restoration, and environmental generational amnesia. My research has expanded to examine risk perceptions (including behavioural intent), value and risk mapping, threat footprints, and the social implications of hazards to conservation.

I am actively recruiting postgraduate students. If you are interested in research in the marine and coastal environment and wish to explore the possibility of undertaking a PhD (or Master) at the University of Waikato, let's have a chat!

Within the marine conservation and sustainability context, the specific areas, the specific areas that I'm interested in are:

  • Seagrass health and restoration
  • Introduced marine species and their management
  • Marine debris
  • Risk and risk perception (regarding coastal and marine issues)
  • Social drivers of environmental impact
