Dr Annabelle Keene has dedicated research interests in geochemistry, pedology and fluvial geomorphology. She holds a Bachelor of Science in Physical Geography, a PhD in Pedology and has published over 20 journal publications and 30 conference papers in research fields of geochemistry and physical geography and environmental geosciences. Annabelle has more than 9 years experience in natural resource and environmental research, investigating acid sulfate soils in coastal floodplains since 1997, and fluvial geomorphology and geochronology from 2003. Her research in these areas has explored landscape-scale processes and the effects of changing climate and human activities. She looks to apply her research to riverine and wetland management and rehabilitation for sustainable ecosystems.
