Background

My research focuses on materials for electrochemical energy systems, with a particular emphasis on electrochemistry, electron microscopy, and dabblings in the application of machine learning in materials discovery.

I joined the School of Mechanical & Mining Engineering at The University of Queensland (UQ) as a Lecturer in 2016 and was promoted to Senior Lecturer in 2020 and Associate Professor in 2023.

I earned my PhD in Chemical Engineering from UQ in 2007. Following this, I spent four years at DTU Energy (Technical University of Denmark) and five years at the Robinson Research Institute at Victoria University of Wellington.

My fundamental research interests include:

  • Operando electron microscopy characterisation for electrochemical systems - electrolysers and batteries
  • Development of novel battery materials, for sodium-based batteries including solid state batteries and anode free battery systems
  • Understanding degradation mechanisms in electrochemical systems - a current focus on carbon dioxide electrolysis systems.
  • Machine learning-driven material design.

My industry facing research interests include

  • Development of printed batteries for health monitoring and logistics applications.
  • Large-scale implementation of electrochemical energy systems for industry.
  • Understanding fire safety for large-scale battery systems.

Research interests

  • Operando Electron Microscopy Characterisation for Electrochemical Systems

    Characterising materials under near-operating conditions provides invaluable insights into their real-world behaviour. In electron microscopy, achieving operando characterisation is particularly challenging due to the high-vacuum environment of the microscope. For battery systems with liquid electrolytes, this requires encapsulating the cell while maintaining electron transparency—a demanding experimental task. However, the ability to observe nanoscale phenomena in real time offers a unique advantage, enabling the development of more efficient and durable battery technologies.

  • Development of Novel Battery Materials

    Sodium-based batteries, which includes solid state batteries and anode-free systems, represent the future of sustainable and high-performance energy storage. A key focus of our research is the development of novel materials to optimise electrode interfaces and enhance cathode performance. By engineering interfaces, we aim to improve slow interfacial kinetics to reduce degradation. These advancements are essential for overcoming current limitations in next-generation battery technologies and enabling their large-scale commercial adoption.

  • Machine learning and robotics in new material design

    Leveraging machine learning for materials discovery is critical in the design of next-generation functional materials. Despite extensive research into new materials for various applications, many commercial systems continue to rely on well-established compositions. With a wealth of experimental data available, machine learning holds significant potential for unlocking the design of superior alternatives. In addition, the development of robotic systems to assist in high-throughput synthesis is accelerating the discovery and optimisation of novel materials. This approach fosters interdisciplinary collaboration, bringing together expertise from fields such as machine learning and robotics to drive innovation in materials science.

  • Understanding Fire Safety for Large-Scale Battery Systems

    As energy storage systems scale up, safety becomes an increasingly critical concern. Research in this area is essential for developing safer battery technologies, mitigating thermal runaway risks, and ensuring regulatory compliance for grid-scale and industrial applications. This work is conducted in collaboration with fire safety experts to assess the unique fire risks associated with large-scale battery systems. By combining expertise, the goal is to develop strategies and technologies that enhance the safety of large-scale energy storage systems.
