G130204MQ102-AP008I am a spatial ecologist with broad research interests and have predominantly focused on coral reef systems.  My ultimate goals are to understand and predict how coastal and marine ecosystems will respond to climate change and develop decision support tools for conservation zoning. My current research focuses on the vulnerability of coral reefs to multiple environmental stressors at multiple spatial scales. This research spans multiple disciplines, using data and tools from remote sensing, hydrology, paleontology, bio-geography, and coral reef biology and ecology. Therefore, in undertaking this research I deal with a broad array of topics, ranging from fundamental theoretical work, through data gathering and manipulation, to developing predictive spatial models of coupled biological and physical systems. I integrate environmental variables with the biological, physiology and ecological responses of corals to generate outputs that aim to support decision-makers, in particular the spatially adaptive management strategies for those involved with the conservation of coral reefs.
