Nature-based rehabilitation science and technology, with a focus on ecological engineering of mine wastes (e.g., AMD-waste rocks, tailings (coal tailings, magnetite tailings, bauxite residues (or red mud), Cu/Pb-Zn tailings)) into earth materials (e.g., soil, engineered rocks) and resilient landforms for cost-effective sustainable rehabilitation at mine waste landscapes.

Professor Huang is a full professor and the group leader of Ecological Engineering in Mining, in the Sustainable Minerals Institute, University of Queensland. Since 2010, Prof Huang has pioneered new concepts and technological framework to manage and rehabilitate mine wastes (e.g., tailings, acidic and metalliferous waste rocks), through putting pedogenesis in engineering nutshell, i.e., eco-engineering of pedogenesis in mine wastes. He is leading an industry-enaged and interdisciplinary research group that is partnered with leading mining companies and empowered by multidisciplinary knowledge and skills on: environmental molecular microbiology, environmental mineralogy, soil science, native plant rhizosphere (micro)biology, soil-plant relations, and bio-chemical engineering of environmental materials (e.g., functional carbon and mineral absorbents, environmental geopolymers).

He is highly experienced in industry-partnered research and translation of knowledge into field-based technologies for tackling large environmental challenges in the mining industry, for example, technologies for tackling global tailings problem. Since 2010, he has led many large and industry-partnered research projects attracting about $21M funding. The research aims to deliver transformative knowledge and practices (i.e., technologies/methdologies) in the rehabilitation of mine wastes (e.g., tailings, mineral residues, spoils, waste rocks) and mined landscapes for non-polluting and ecologically and financially sustainable outcomes. Prof Huang has successfully demonstrated innovative methodology and technology to achieve nature-based outcomes in treating and rehabilitating tailings and waste rocks. Prof Huang’s research program was featured in Rio Tinto’s media releases as one of the four most successful global R&D partnerships in 2024. Prof Huang led the development of the first field-feasible technology to treat and dealkalize alkaline bauxite residues for sustainable rehabilitation. His industry-partnered research was recognised in 2019 UQ’s Partners in Research Excellence Award (Resilient Environments) (Rio Tinto and QAL). Prof Huang is also developing new knowledge and technologies for achieving non-polluting and ecologically sustainable rehabilitation of, for example, coal mine spoils and tailings, Fe-ore tailings, bauxite tailings (from mining bauxite), and Cu/Pb-Zn tailings.

Julie’s research is mainly focussed on gas-water-rock core reactivity at reservoir conditions using experimental, field, and geochemical modelling techniques. Recent projects have been in the application of carbon dioxide geological storage in which CO2 is captured and stored in formations generally contained by low permeability cap-rock. The safe containment of the injected CO2 and the potential changes to rock porosity, permeability, and water quality should be determined. Recent and current projects with a focus on a demonstration site in the Surat Basin (Precipice Sandstone) include the impacts of impurity or acid gases present in industrial CO2 streams (collaboration with D. Kirste, SFU), inducing carbonate precipitation (in collaboration with S. Golding), and understanding dissolved metal sources and fate. Julie has also worked closely with the CO2CRC, CTSCo, Glencore, SEAL, the NSW government, CI-NSW, and ANLEC R&D, and provided expert opinion to the Queensland Government, and input to Environmental Impacts Assessments.

Julie is currently working with landholders, the QLD regional government, RDMW, councils and industry to understand the sources of methane in aquifers of the Great Artesian Basin, especailly those overlying coal seam gas reservoirs (CSG) (with Arrow Energy, SANTOS, APLNG, H. Hoffman, K, Baublys).

Other projects include gas-water-rock or acid-rock reactivity that modify nano-porosity and gas flow in gas or oil bearing shales.

Julie Pearce graduated with an MCHEM (Hons) degree in Chemistry from the University of York, UK. She then moved to the University of Bristol to complete a Ph.D. in 2007 focusing on laser spectroscopic studies to understand the detailed reaction dynamics of atmospheric processes. From 2007 – 2009 she accepted a Japan Society for the Promotion of Science Postdoctoral Fellowship, hosted at Nagoya University, Japan. There she measured delta 13C and delta 18O isotopic signatures of CO2 simultaneously in real time in the atmosphere using a laser spectroscopic technique to understand anthropogenic and biogenic sources of CO2. After taking a career break to travel in 15 countries in Asia, she moved to Brisbane in 2010 where she is enjoying the surrounding natural beauty of Queensland.

Cassandra is a Senior Research Fellow at the Queensland Alliance for Environmental Health Sciences (QAEHS), joining the group in 2019. She is the microplastics project lead in the Minderoo Centre-Plastics and Human Health, investigating human exposure to microplastics and developing new methods for detecting micro and nanoplastics in human matrices. Her other research interests include the impact of tyre road wear particles and their chemical additives on the environment and developing novel biomonitoring methods for assessing human exposure to chemicals of concern.
