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.
