Paul Dennis leads an exciting research group that applies cutting-edge technologies to understand the roles of microorganisms and their responses to environmental change.

He is also a passionate educator and public speaker who advocates for the importance of biological diversity and evidence-based environmental awareness. He has talked about his research on ABC Radio and a range of other media outlets.

His teaching covers aspects of ecology, microbiology, plant and soil science, and climatology. He considers these topics to be of fundamental importance for the development of more sustainable societies and takes pride in helping others to obtain the knowledge and skills they need to build a better future.

Paul's research has taken him to Antarctica, the Amazon Rainforest, high mountains and oceans. The approaches used in his lab draw on a wide range of expertise in molecular biology, ecology, statistics, computer science, advanced imaging and soil science. He applies these skills to a wide-range of topics and systems including plant-microbe interactions, Antarctic marine and terrestrial ecology, biogeography, pollution and human health.

Science and technology of ecological engineering of ferrous and base metal mine tailings (e.g., magnetite tailings, bauxite residues (or red mud), Cu/Pb-Zn tailings) into functional technosols and hardpan-based soil systems for sustainable tailings rehabilitation: geo-microbial ecology, mineral bioweathering, geo-rhizosphere biology, technosol-plant relations in mined environments. Championing nature-based solutions to global mine wastes challenges.

Longbin Huang is a full professor and a Program leader in The University of Queensland, leading a research program of "Ecological Engineering in Mining" to develop naure-based methdology and technology, for assisting the world's mining industry to meet the global tailings challenge. Driven by the passion to translate leading knowledge into industry solutions, Longbin has pioneered transformative concepts and approach to tackle rehabilitation of mine wastes (e.g., tailings, acidic and metalliferous waste rocks). Recent success includes the "ecological engineering of Fe-ore tailings and bauxite residue" into soil, for overcoming the topsoil deficit challenge facing the mining industry. Scaled up field trials have been going on to deliver the much-needed technology into field operations. Long-term and multi-site based field trials have demonstrated for the first time, the field-feasibility to accelerate nature-based soil formaiton processes for developing tailings into adaptive and sustainable soil (or technosol) capable of sustaining plant community growth and development (https://www.youtube.com/watch?v=6VzfiWL-8UI&t=4s).

The program consists of a group of researchers with leading knowledge and research skills on: soil/geo-microbial ecology, environmental mineralogy, bioweathering of minerals, native plant rhizosphere (micro)biology, soil-plant relations, and environmental materials (such as biochar and environmental geopolymers). It 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.

In partnership with leading mining companies, Longbin and his team have been focusing on developing game-changing knowledge and technologies of tailings valorisation for achieving non-polluting and ecologically sustainable rehabilitation of, for example, coal mine spoils and tailings, Fe-ore tailings, bauxite residues (or red mud), and Cu/Pb-Zn tailings. Leading the global progress in bauxite rehabilitation, Longbin and his team are currently taking on field-scale research projects on bauxite residue rehabilitation technologies at alumina refineries in Queensland (QAL- and Yarwun refineries) and Northern Territory (Gove refinery).

Longbin's industry-partnered research was recognised in 2019 UQ’s Partners in Research Excellence Award (Resilient Environments) (Rio Tinto and QAL).

Denys Villa Gomez holds a joint appointment at the University of Queensland as Senior Lecturer at the School of Civil Engineering and as a Research Fellow at the Australian Institute for Bioengineering and Nanotechnology. She obtained her PhD at the world-leading institute’s IHE-Delft/Wageningen University, The Netherlands in 2013. She applies advanced methodologies such as omics approaches and micro spectral tools to develop biotechnology processes that reduce carbon emissions and recover resources from mine waste and wastewater. She is the leader of the key area “Synbio Mining” within the recently created UQ Biosustainability Hub and chief investigator at the ARC Training Centre in Critical Resources for the Future. She has published over 40 peer-reviewed journal and conference papers cited more than 500 times, and has served as editor and reviewer for leading journals and advisory roles in industry and scientific committees (e.g. International Mine Water Association).
