Dr Hugo Olierook

Senior Research Fellow

Hugo places geological problems into a temporal context. By adding time to 3D problems, he helps the mining industry explore for critical metals, evaluates the drivers of past climatic crises, and explores tectonics throughout Earth’s history.

Hugo joined the Timescales team in 2019.

Dr Giada Bufarale

Research Fellow

Giada’s research focuses on understanding the origin of phosphate-bearing sediments in northern Angola and examining how the post-rift structural and tectonic history has impacted their deposition and preservation.

Dr Janne Liebmann

Research Fellow

Janne is currently building a Pb isotopic map of Australia. She previously focussed on a series of global events that occurred 2-3 billion years ago and permanently changed the face of the Earth (e.g. the first significant build-up of oxygen in the atmosphere and the emergence of continents above sea-level).

Janne joined the Timescales team as a PhD student in 2018, and became a staff member in 2021.

Dr Maximilian Dröllner

Research Associate

Max aims for a re-evaluation of the paradigm of heavy mineral sand deposit formation. An attempt will be made to present a universal model of deposit genesis, i.e. quantifying the fundamental geological controls.

Max joined the Timescales team as a PhD student in 2020, and became a staff member in 2023.

Dr Andreas Zametzer

Research Associate

Andi designs and executes projects for industry partners and government organisations and does research on various geological topics ranging from crustal evolution to the formation mechanisms of heavy mineral sands deposits.

Andi joined the Timescales team as a PhD student in 2020, and became a staff member in 2023.

Taryn Scharf

Research Associate

Taryn’s research applies geocomputing to the deconvolution of mineral grain histories. This work looks to develop new analytical tools that can be integrated with standard geological approaches for basin analysis and heavy mineral sand exploration.

Taryn joined the Timescales team as a PhD student in 2020, and became a staff member in 2024.


Isabel Zutterkirch

PhD Student

Isabel is conducting research on the provenance of sedimentary rocks in Western Australia addressing their sediment transportation pathways derived from isotope (U-Pb, Lu-Hf, Pb-Pb, (U-Th)/He) fingerprinting.

Isabel joined the Timescales team in 2020.


Kathy Kuper

PhD Student

Kathy’s research looks at mapping the Nd isotopic variation throughout the Fraser Zone of the Proterozoic Albany Fraser Orogen, as a means to reduce exploration risk on the margin of the Archean Yilgarn Craton in Western Australia by tracking juvenile domains.

Kathy joined the Timescales team in 2021.

Anthony Clarke

PhD Student

Tony’s research aims to establish apatite as a new tool to track the evolution of the continental crust. Current continental crust development models rely on the mineral zircon. However, zircons only record the history of evolved rocks. Therefore, Tony’s research examines apatite which forms in less evolved mafic rocks. A detrital apatite database of Pb-Nd (model) ages is being developed and integrated with the zircon record to provide a more holistic description for how our planet developed.

Tony joined the Timescales team in 2021.

Lucy Mathieson

PhD Student

Lucy’s research aims to reduce mineral exploration risk in Australia by developing a new tool to track fluid mobility in space and time using Pb-loss mapping. Lucy utilizes the Pb-loss process in zircon to model and evaluate radiogenic-Pb mobility across Australia to determine whether there is both a spatial and temporal relationship between Pb mobility and other geological processes including, for example, mineralization, fault density and dyke emplacement.

Lucy joined the Timescales team in 2021.


Priyanjan Datta

PhD Student

Priyanjan uses in situ Pb isotope data from K-feldspar in granitoids (and potentially pyroxenes in mafic rocks) in combination with whole-rock Pb isotope and trace element (e.g., U and Th) compositions of a range of rock types spanning eastern Australia to fingerprint the source characteristics and its evolution through space and time.

Priyanjan joined the Timescales team in 2023.


Jiankang Yi

PhD Student

Jack applies apatite geochronology to constrain the accurate age of salt, the internal stratigraphy, and the burial and exhumation history of rock salt bodies in major salt-bearing basins across Australia (e.g., Canning Basin, Adavale Basin). 

Jack joined the Timescales team in 2023.
