Introduction
I am a member of the Management Committee for the Institute for Sustainability, Energy, and Resources at the University of Adelaide (2023-2024) and a Superstar of STEM through Science and Technology Australia (2023-2024).
As a Postdoctoral Research Fellow and a recipient of the prestigious Global Talent Visa, my current research applies my expertise in sedimentology, stratigraphy, and salt-sediment interaction to subsurface hydrogen storage and exploration and critical mineral deposits.

Globally, many salt basins host highly productive fossil fuel resources and provide excellent opportunities for developing economically viable clean energy systems such as (1) energy storage in salt caverns, including hydrogen, helium, natural gas, and other economic gases; (2) permanent sequestration of carbon dioxide; (3) development of geotherma...
As government policy, consumer markets, and global geopolitics rapidly shift, it will be imperative that energy companies, universities, and government organizations have access to research that addresses the subsurface development of energy. A key area of research for the energy transition is related to the precipitation, deposition, and dia-piris...
When professional organizations allow gender inequity to persist, they continually lose talented, valuable individuals who enrich and lead their groups and drive innovation. 2 (GSA). All three of these societies (AAPG, AGU and GSA), whilst based in the USA, have substantial international membership. There is clear evidence of continued gender inequ...
Patawarta Diapir, located in the Central Flinders Ranges, South Australia, has been interpreted as a single allochthonous salt sheet containing Tonian-aged igneous and layered evaporite sedimentary intrasalt inclusions derived from the Callanna Group. Using detailed field mapping, petrographic analysis, and lithostratigraphic correlation within Pat...

When professional organizations allow gender inequity to persist, they continually lose talented, valuable individuals who enrich and lead their groups. According to membership data collected by the American Association of Petroleum Geologists (AAPG), the American Geophysical Union (AGU), and the Geological Society of America (GSA), there is eviden...
The Flinders and Willouran ranges of South Australia contain over 20 examples of exposed allochthonous salt sheets and canopies comprising the Callanna Group megabreccias. The identification of a given diapir or portion of a diapir as allochthonous is well documented in some cases but more speculative in others. Here we summarise most of the exampl...
The 'rim dolomite' of South Australia's Central Flinders Ranges is a prominent ridge-forming, layered dolomitic and siliceous unit. The rim dolomite is interpreted to be a lateral caprock found exclusively at the salt-sediment interface between the Patawarta diapir and the Ediacaran-aged Bunyeroo Formation. Lateral dolomite caprock is defined by th...
The northern Flinders Ranges and eastern Willouran Ranges, South Australia, expose Neoproterozoic salt diapirs, salt sheets and associated growth strata that provide a natural laboratory for testing and refining models of allochthonous salt initiation and emplacement. The diapiric Callanna Group (~850–800 Ma) comprises a lithologically diverse asse...
Outcrops of the Neoproterozoic Callanna Group (∼850-800 Ma) comprise an assemblage of brecciated rocks throughout the northern Flinders Ranges and the eastern Willouran Ranges, South Australia, and represent salt bodies in which the evaporite is now absent. Using field relationships and stereonet analysis, we demonstrate that the breccia bodies for...
Parts of two third-order Neoproterozoic (Marinoan) depositional sequences are documented in the Wilpena Group (Wonoka Formation and Bonney Sandstone) at Patawarta diapir, located in the central Flinders Ranges, South Australia. These sequences represent an overall regressive succession transitioning upwards from outer to middle wave-dominated shelf...
We present new WDXRF trace-element data from products of the May 1915
eruption of Lassen Peak in Lassen Volcanic National Park (LVNP),
California. Four main rock types are present in the 1915 deposits: light
dacite, black dacite, dark andesite and andesite inclusions in light and
black dacites. Trace-element data collected for this study confirm th...

I currently have two graphs, but the data is densely clustered so I can not see the details of the Neoproterozoic.

Failed methods:
Ar39/Ar40 isotopes
Dating Zircons
Nd-Sm isotope geochronology
Any ideas, advice or experience would be greatly appreciated!
