Research Interests

My research interests span the areas of ecological and evolutionary genetics and genomics in a range of marine organisms including coral reef fishes, mangroves, corals, and their symbiotic communities of bacteria and dinoflagellate algae (zooxanthellae).

My current research focus is on the ecological and evolutionary genetics and genomics of coral symbioses. In particular, I am interested in gene expression variation in natural and stressed coral populations with the view of identifying key genes and pathways associated with coral bleaching. This research further aims to quantify variation in gene expression of reef building corals at a range of scales including within and among genotypes of coral host and zooxanthellae, times of day, and populations.

In collaboration with colleagues and students I use molecular tools to examine the population structure, patterns of connectivity and effective population sizes of zooxanthellae, corals and reef fishes in natural and disturbed systems. This research involves the development of molecular markers to compare populations and/or species with different ecological attributes such as level of temperature tolerance, ecological specialization, dispersal potential, range size, etc.

I examine the factors determining population structure at local and regional scales in a range of coral reef organisms.
