I am driven by the fundamental desire to understand anthropogenic impacts on marine ecosystems, and to facilitate management in a rapidly depleting ocean. My research is currently focused on coral reef ecosystem function (namely on the Great Barrier Reef), and human-driven shifts in ecosystem dynamics. While ‘biodiversity’ has historically been considered as pivotal to maintaining ecosystems, it is becoming more evident that a small subset of species is particularly important in supporting ecosystem processes, functions and services. My research aims to identify these important species to make targeted recommendations for management.

My key interests are in marine invertebrates, especially the Echinodermata. These [less-charismatic] organisms are largely understudied compared to the more conventional reef species like fish and corals, but are highly important in ecosystem functions and services – from their population and ecosystem dynamics (e.g. the crown-of-thorns starfish), to their direct commercial importance (e.g. sea cucumber fisheries; trepang).
