Dr Anthony Halog: Expert in Circular Economy, Life Cycle Thinking, and Sustainable Systems

Dr. Anthony B. Halog is a professor at the University of Queensland specialising in circular economy, sustainability engineering, industrial ecology, and life cycle assessment (LCA/LCSA). His current work focuses on designing low-carbon, net-zero, and resource-efficient systems to address climate change, waste reduction, and sustainable development.

Dr. Halog works across energy, materials, food, waste, and policy systems, applying systems thinking, life cycle sustainability assessment, digital twins, and artificial intelligence for sustainability. His research helps governments, industries, and communities make evidence-based decisions that reduce emissions, improve resource efficiency, and avoid unintended environmental impacts.

A core focus of his work is transforming linear value chains into circular value chains, supporting green hydrogen, bioenergy, circular bioeconomy, agricultural waste valorisation, waste-to-energy, and sustainable materials. These solutions contribute to decarbonisation, climate resilience, sustainable supply chains, and the green economy.

Key areas of expertise

• Circular economy and industrial ecology

• Life cycle assessment and sustainability metrics

• Green hydrogen, bioenergy, and clean energy transitions

• Sustainable waste management and circular bioeconomy

• Systems modelling, AI-enabled tools, and sustainability policy

Dr. Halog collaborates with policymakers, industry partners, SMEs, and Indigenous communities in Australia and internationally to deliver practical climate solutions and support the transition to decarbonised circular economies.

Professor White leads the Quantum Technology Laboratory at UQ, which he established in 1999, and is an Australian Research Council Laureate Fellow. He is internationally recognised for research in quantum science and technology, and is interested in all aspects of quantum weirdness. He is a Fellow of the Australian Academy of Science, the American Physical Society, and Optica. Andrew’s research spans: quantum foundations; production, manipulation and exploitation of quantum states of light, both in conventional optics and nanophotonics; and utilising quantum technology, be it in quantum computation, quantum communication, quantum sensing, or neuromorphic computing. Details can be found at the Quantum Laboratory website.

Professor White has worked with twenty-two postdoctoral researchers since 2001, five of whom received ARC Discovery Early Career Researchers Awards whilst working in his lab, six receiving Marie Skłodowska-Curie Fellowships subsequently and one a Erwin Schrödinger Fellowship. He has supervised more than 40 postgraduate students, who have received an array of awards including a Rhodes Scholarship, three Springer PhD thesis prizes, Australian representative at the Lindau Nobel Meeting, the only-ever runner for the Australian Institute of Physics Bragg Medal, and UQ Medals and Valedictorian, to name but a few.

Bio: Andrew was raised in a Queensland dairy town, before heading south to the big smoke of Brisbane to study chemistry, maths, physics and, during the World Expo, the effects of alcohol on uni students from around the world. Deciding he wanted to know what the cold felt like, he first moved to Canberra, then Germany—completing his PhD in quantum physics—before moving on to Los Alamos National Labs in New Mexico where he quickly discovered that there is more than enough snow to hide a cactus, but not nearly enough to prevent amusing your friends when you sit down. Over the years he has conducted research on various topics including shrimp eyes, nuclear physics, optical vortices, and quantum computers. He likes quantum weirdness for its own sake, but his current research aims to explore and exploit the full range of quantum behaviours—notably entanglement—with an eye to engineering new technologies and scientific applications. He is currently Director of the Centre of Engineered Quantum Systems, an Australia-wide, 14-year long, research effort by more than 250 scientists to build quantum machines that harness the quantum world for practical applications.
