I am a sedimentologist and taphonomist specialising in sand dunes, swamps and bogs.
I am interested in the environment of the Quaternary age (the last 2 million years) and the animals that lived at the time, known as megafauna. These animals include the extinct giant Diprotodon (like a giant wombat), Sthenurus, Macropus titan (giant kangaroo) and Thylacoleo (marsupial lion).
My Masters work involved studying a mass of vertebrate fossil megafaunal bones deposited in a coarse sedimentary ‘raft’ at Lancefield Swamp, north of Melbourne. This included a study of the Quaternary local climate and fluvial conditions that would have influenced the deposition.
As part of this study I also examined all fossil bones and mandibles found in the swamp for signs of disease to determine if climatic stress may have influenced the demise of local fauna, and also determined the number of cut marks (either from predation or indigenous hunting practices) in all elements.
My PhD focused on King Island, Bass Strait, where I explored the palaeosol (fossil soil) layers in the sand dunes that ring most of the Island. I aimed to link these deposits to Late Quaternary to Holocene sea level changes and storm surge events.
My PhD also included a comparison the leg bones (tarsometatarsi and tibiotarsi) of the now extinct dwarf King Island Emu (Dromaius ater) to the now extinct Kangaroo Island Emu (Dromaius baudinianus) in view of resolving the relationship between these two isolated species.
My current research interests are in Quaternary environmental changes, megafaunal extinction processes and taphonomical determination related to palaeontological sites.
Previous to joining Deakin, I worked in the exploration mining industry.
My main interest is in the link between climate change and the megafaunal extinctions during the Quaternary in Australia.
I have done research at Lancefield Swamp in Victoria and King Island, Tasmania.
I love swamps sand dunes and bogs - strange that I am.
Sedimentary (fluvial) environments, geo-concentration processes (south-eastern Australia), taphonomy, palaeontology.
These include lateritic, placer, dune, swamp, riverine and lacustrine deposits, palaeosol development and Quaternary/Holocene past environments, faunas and climatic processes.
