Senior Lecturer, Spatial Science

    Biography

    My primary area of research is the application of geospatial technologies (e.g., Geographic Information Systems and remote sensing) to the study of Earth’s environment and natural processes. I am particularly interested in coral reef processes and geomorphology.

    I first developed an interest in coastal and coral reef geomorphology (how reef features form and evolve) during my undergraduate degree at James Cook University where my honours research examined the impacts of harbour infrastructure on reef islands in the Torres Strait. I later completed a Masters in Geospatial Technologies in Europe with a particular focus on spatial data interoperability. After a few years working as a spatial analyst in the environmental consultancy industry I decided to return to coral reef research and completed a PhD at The University of Sydney. I enjoy multidisciplinary research and the opportunity to combine field work with a variety of geospatial technologies to better understand the world and our part in it. I am passionate about inclusivity and equity in teaching and research and am an Associate Investigator with the Centre for Indigenous and Environmental Histories and Futures.
