1Although all aspects of deep-sea biology interest me, I am more fond of some than others. My current research interests are:
Biodiversity and Deep-Sea Mining

The Clarion-Clipperton Zone (CCZ) is a large area in the Pacific Ocean where deep-sea mining may one day occur. It is also one of the least-explored areas on our planet. My research over the last two years has been trying to understand what megafauna live in the CCZ. Only by understanding what lives here, can we effectively manage resource extraction.
Hydrothermal Vents and Cold Seeps

Hydrothermal vents and cold seeps are some of the most enigmatic deep-sea habitats. They are remarkable for their abundance of life, their wealth of new species and because energy is made by chemosynthesis rather than photosynthesis. I have been fortunate to work at several vent and seep sites including the world’s deepest vents and the world’s most southerly vents.
Organic Falls

When a whale dies or tree is washed out to sea, it gradually sinks to the deep seafloor. The arrival of a carcass or piece of wood prompts a feeding bonanza with animals coming from near and far for a meal and shelter. This is what is termed an organic fall. Organic falls, specifically whale falls and wood falls, are very special to me as that was what my Ph.D. research focused on.
My Deep Sea, My Backyard
70% of nations have deep-sea environments within their maritime Exclusive Economic Zones, yet only 16% of them are able to explore those environments. This pilot project will begin to change this by empowering nations to explore their own deep-sea backyards using low-cost technology, while building lasting in-country capacity.
