Research Interests
- Biology and Ecology of Reef Corals
- Life Histories of Modular Organisms
- Evolutionary Biology/Molecular Ecology of Corals
My current research activities focus on questions concerning the capacity of corals to cope with climate change through their potential to form symbiosis with a range of Symbiodinium (zooxanthellae) clades that affect their physiological performance, specifically their thermal tolerance. A second research focus is understanding the ecological significance of coral disease on the Great Barrier Reef and the links between disease and ocean warming.
Other research areas in which I have published include: Breeding synchrony and comparative gametogenic studies of corals; Geographic patterns in mass spawning; Proximate factors involved in synchronising mass spawning; Larval dispersal of mass spawning corals; Latitudinal gradients in coral recruitment; Separating genotypic and phenotypic components of morphological variation; Histocompatibility responses and intra-specific competition in corals; Growth strategies leading to morphological variation in corals.
Recent and Currently Supervised PhD Topics
- Reassessing the status of coral species using breeding, morphometric and molecular studies
- The behaviour and ecology of coral larvae
- Reproductive senescence in corals
- Upper thermal limits and acclimation in corals
- Impact of bleaching on coral reproduction
- Impact of bleaching on soft coral assemblages
- Effects of nutrients on the early life history stages of corals
- The role of particulate feeding in the energy budgets of corals
- Tissue thickness as an indicator of coral health
- Chemical ecology of the soft coral-zooxanthellae relationship
Future PhD Directions
- Exploring species boundaries in corals using breeding, morphometric and molecular studies
- Recovery of coral assemblages following bleaching
- Effects of temperature and photoperiod on reproduction in mass spawning corals
- Biology and ecology of reef corals
- Life histories of modular organisms
