My research interests focus on applied marine ecology that will directly benefit communities in New Zealand and the wider Pacific region.  I am committed to mentoring up and coming Māori and Pacific Nations’ marine scientists to directly increase the research capability within iwi and Pacific Nations’ communities. 

The science capability of Te Rūnanga o Toa Rangatira is being directly built through the ongoing involvement of one of their rangatahi with my current research.  I am also a longstanding member of Te Rōpu Āwhina whānau at Victoria University.   Both my PhD and Postdoctoral research have been funded by the Foundation for Research Science and Technology (now the Ministry of Science and Innovation).

Research Interests

Land-based effects on coastal invertebrate fisheries of cultural and economic significance

With increasing development on land (mining, deforestation, dairy conversion) resulting in increased sediments making their way to the coastal marine area, the effects of sedimentation may reduce the resilience of paua and kina populations to fishing.  My current research investigates a range of responses (fertilisation success, growth, mortality, feeding behaviour) to sedimentation across various life-history stages for paua and kina, and will also investigate changes in morphology that may occur in response to sedimentation (e.g., morphological changes in feeding structures).  This work will ultimately increase understanding of the effects of sedimentation on paua and kina, identifying life-history stages that may be more vulnerable to sedimentation than others, and ultimately have implications for both fisheries and catchment management.

The effectiveness of marine protected areas

Marine protected areas (MPAs) are widely used as tools for both conservation and fisheries management.  However assessments of many MPAs may be confounded by differences in habitat between ‘Impact’ (ie, MPA) and ‘Control’ sites, leading to erroneous conclusions regarding MPA effectiveness.  I conducted a simultaneous assessment of six Ra’ui (traditional marine protected areas) in the lagoon of Rarotonga, Cook Islands, and developed a new approach incorporating habitat differences between ‘Impact’ and ‘Control’ sites into MPA assessments.  My work will aid better design of monitoring programmes and facilitate improved MPA design.
