I am an ecologist with a research program focused on exploring the fundamental principles that underpin the structure and function of biogenic habitats (e.g. sponge grounds, coral reels, oyster reefs, seagrass beds). I use a combination of observational and experimental approaches to elucidate the role that habitat forming species play in maintaining biodiversity and ecosystem function in the Anthropocene. I apply the findings of my research to tackle pressing issues in marine conservation by working directly with fisheries and resource managers to identify habitats in need of protection and developing monitoring methods grounded in cutting edge research. To this end my research is focused in three broad areas: 1) revealing the factors that maintain biodiversity and ecosystem function, 2) identifying drivers of decline in biogenic habitats, and 3) developing monitoring and restoration techniques for biogenic habitats.


  • Developing passive acoustic methods to monitor reef habitats
  • Determining the prevalence and impacts of anthropogenic noise in reef habitats
  • Evaluating the role of ecological memory in ecosystem response to multiple stressors
  • Assessing the impacts of Hurricane Dorian on the coastal ecosystems of the Northwestern Bahamas
  • Developing new markets to increase demand for Invasive Carp
