From cool water help forests to diverse coral reefs, I have 1500+ logged dives over 5+ years as a scientific diver. I have worked in a range of environmental conditions around the world with a majority of my research conducted in the Oceania region .

Over 2014 and 2015 I joined a team of scientists from the Khaled Bin Sultan’s Living Oceans Foundation as part of their Global Reef Expedition.  On board research vessel The Golden Shadow, I worked as a fish surveyor on expeditions on The Great Barrier Reef, Solomon Islands, Palau, Maldives, and The Chagos Archipelago.

In 2013 I completed a two week ADAS course in scientific diving with an emphasis on working safely and effectively as members of an integrated occupational dive team. During the course I was assessed on the use of a variety of modern diving equipment including full face masks with effective communications, sampling and survey tasks.

Over 2013 and 2014 I worked alongside a range of marine scientists and received training as a fish surveyor in Raja Ampat, West Papua as part of my year as the Australasian OWUSS Rolex Scholar.

In 2012 I moved to Perth to begin a fieldwork intensive research project involving habitat forming seaweeds in South Western Australia.


During a marine heatwave in the region in the summer 2011,  seawater temperatures soared above annual averages. A local canopy forming seaweed (Scytothalia dorycarpa) was particularly impacted contracting it’s range up to 100km poleward.

Through field observations and culture growth experiments,  my research investigated the temperature sensitivity, reproductive timing and recruitment success of this widespread foundation seaweed. My research findings were published in Marine Ecology Progress Series journal in 2014.

At the completion of my fieldwork I was awarded the University of Western Australia’s Ray Hart Memorial Scholarship for demonstrating a commitment to developing skills in field ecological research and a commitment to apply field research to achieve a broad and pragmatic insight into interdisciplinary ecological studies
