Research Interests

Geomorphology and sedimentology, especially in the drylands of Australia and southern Africa. Particular research themes include: anabranching rivers; floodplains and floodouts; wetlands in drylands; channel-vegetation interactions; bedrock-influenced rivers; controls on gully erosion; long-term fluvial landscape development; palaeoenvironmental change; global climate change and the Anthropocene; and the use of drylands on Earth as analogues for Martian surface environments.

: Julian Ruddock (co-supervised with Professor John Harvey, School of Art)

: Zacc Larkin (Macquarie University, Sydney: co-supervised with Dr Tim Ralph and Professor Kirstie Fryirs)
