PROFILE

Professor Eun-Jung Holden

Started at UWA: 1989

Unearthing new ways to mine data

My passion is to achieve research impact beyond academia, specifically in transforming industry practice in geodata analysis through innovative and advanced data science applications.Professor Eun-Jung Holden

Professor Eun-Jung Holden is the Director of UWA Institute of Data and the leader of Centre for Data-driven Geoscience (CDG) at the School of Earth Sciences at UWA. She has leading expertise in data science applied to geoscience. Her research develops advanced machine learning, image analysis and visualisation methods to automate or semi-automate the interpretation of geoscientific data (geodata). Professor Holden’s multi-disciplinary research spans the boundaries of computational science and geoscience, and links academia with industry.

Professor Holden came to UWA as an international student from South Korea in 1985. She was trained and worked as a computer scientist at UWA. Her postgraduate and postdoctoral research focused on developing computer vision and visualisation algorithms for human motion recognition.

In 2006, she made a transition to geoscience at UWA. She established and currently leads the Geodata Algorithms Team that fosters a unique level of multi-disciplinary training and end-user focused research. 

Through their innovative, transformational and interpretive data science solutions for geoscience end users, the team’s research achieved global research impact. Three suites of geodata analytics algorithms were commercialised in partnership with the world’s leading software vendors, namely CET Grid Analysis and CET Porphyry Detection extensions for Geosoft’s Oasis Montaj, in partnership with Geosoft (based in Canada); and Image Structure and Interpretation module for Advanced Logic Technology (ALT)’s WellCAD, in partnership with ALT (based in Luxembourg).

These products have been sold globally across the minerals and oil & gas industries.

Professor Holden has been leading major data science projects with Rio Tinto Iron Ore (RTIO) in recent years, including previous Data Fusion Projects (2018-2021, $3.6m) and the current project that applies data science to objectively log geology for mine geology (2022-2025, $6.1m).

This industry engagement resulted in the development of deployable machine learning methods and tools to analyse stratigraphy and their material compositions using diverse types of drill hole data, which resulted in three patent applications.  The CDG team at UWA uses machine learning, computer vision, spatial modelling and optimisation techniques to integrate diverse drill hole data including spectral, image, geochemistry and geophysics data to model material compositions, geomechanical proxies and their spatial distribution.  The team also develops advanced and interactive visualisation methods and tools to assist the mine pit mapping of geology in virtual reality.
