Dr Holly East

Assistant Professor

Department: Geography and Environmental Sciences

I undertake research at the intersections between geomorphology and ecology in tropical coastal environments, particularly within seagrass and reef island systems. Specifically, my research is focussed on: (1) reconstructing the development of coral reef islands over millennial to decadal timescales in relation to past environmental change; (2) quantifying reef sediment budgets and contemporary reef-to-island connectivity; (3) understanding seagrass systems in reef island settings, particularly their spatial dynamics, ecosystem services, and relationships with anthropogenic activities; and (4) use of geospatial analysis, through GIS and remote sensing, to improve our understanding of coastal environments.

Research Themes and Scholarly Interests

My research interests are focused on the interface between geomorphology and ecology in��tropical coastal environments, particularly within seagrass and reef island systems. My recent work has included reconstructions of past reef island evolution in relation to environmental change, calculation of reef sediment budgets, and analyses of connectivity between seagrass meadows and reef islands.
