We study reef-forming corals, which sustain the productivity and biodiversity of coral reef ecosystems. Our goal is to understand how environmental conditions shape the form and function of the coral ‘holobiont’ (the coral and it’s associated microbial communities) and therefore how environmental stressors and climate change will impact coral reefs. We research from organism scale molecular signatures to broad scale ecological interactions and specialise in advancing technical solutions to meet our goal. The outcomes directly support model development to more accurately inform the future form and function of reef forming coral communities.

Research Interests and Capabilities
Coral reef management: An increasing focus is applying knowledge gained from core research into coral reef management practices and policy. For example, identifying areas with high conservation value (e.g. reef systems thriving under natural extremes, source reefs) and developing improved targeted management frameworks. Our core research also immediately applies to developing more innovative management strategies, e.g. hardy species or populations for assisted migration and/or out-planting, and developing of bio-optical tools (and metabolic traits) based diagnostics of stress.
Coral stress ecophysiology: Understanding the patterns and processes that regulate coral susceptibility to stressors, such as eutrophication, global warming and ocean acidification is a key goal for our group. We work across molecular, cellular and organismal (physiological) scales to identify the primary components that are affected by stressors but also how secondary metabolite production (e.g. reactive oxygen, volatile gases) regulates the stress response.
Coral bio-optics and photobiology: Non-destructive techniques to quickly and easily examine coral health are essential to understand the impact of stressors. We specialise in developing bio-optical (and active chlorophyll fluorescence) techniques to advance measurements and monitoring of coral productivity/health. We apply these techniques to a wide range of questions; for example how light availability shapes the biology of corals and their algal symbionts.
Microbial processes and biogeochemical cycling: Corals are profoundly influenced by the composition and function of the bacterial community that lives within and around their tissues. We examine the nature of the microbe-coral interactions, what drives them and consider the implications to long-term coral fitness. We employ a variety of molecular, microbiological and ecogenomic approaches, including metagenomics and metatranscriptomics, to examine the composition and functional capacity of the microbial assemblages associated with healthy, stressed and diseased corals. Also, development and application of sensors to examine how such interactions influence cycling of molecules (CO2, O2, Ca) and to rapidly identify particular microbes of interest (e.g. pathogens).
Symbiodinium physiology and life history: Symbiodinium sp. diversity is a key factor regulating coral fitness. We focus on understanding functional diversity amongst Symbiodinium genotypes of physiological, biochemical and molecular traits, and ultimately how this contributes to the susceptibility of host corals to stress. This focus is tied to examining the life history dynamics between in- and ex-hospite Symbiodinium populations.
Modelling coral responses to environmental change: Our various physiological observations and experiments are closely linked to parameterising and therefore developing/implementing predictive models. Activities range from organism-scale (mechanistic/physiological) to community-scale (ecological) models and numerical simulations to more broadly examine the response of coral species and communities to environmental change.
