MSc (Ecology), Otago
PhD (Ecological Sciences), Old Dominion University (USA)

Research interests

My primary research interests are in fisheries restoration and management for long term sustainability. I integrate a number of research areas, including stock enhancement, marine ecology, marine policy, fisheries regulation, and indigenous knowledge, and pair scientific methods (empirical field observations, laboratory experimentation, and computer modelling) with policy analysis and legislative review.

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.
