My research is focussed on genetic diversity in ecological systems – what can it reveal about population ecology, what effect does it have at the community and ecosystem levels, and how can we utilise it most effectively for biodiversity conservation? My work centres on critical conservation issues including ocean acidification, habitat restoration and disease, and incorporates population genetics, microbial ecology, and gene expression approaches.
My primary study system is marine sponges and the rich communities of microbes that inhabit their tissues, known as microbiomes. I use a holistic approach to understand sponge-microbiome relationships, and how their diversity affects resilience and ecosystem processes in the face of environmental change.
