Researcher biography

Zhengdong Han obtained a BEng (Hons) in Environmental Engineering at Harbin Institute of Technology (China, 2007) before obtaining his PhD from The University of Queensland in 2022.

Zhengdong was a registered environmental engineer in the Chinese state key environmental radiation monitoring laboratory and worked on the monitoring and assessment of the environment around abandoned uranium mines and nuclear power plants.

Currently, Zhengdong is a Postdoc Research Fellow in Geochemistry and Environmental engineering at the W.H. Bryan Mining Geology Research Centre within the Sustainable Minerals Institute. He is involved in several projects on mining waste reprocessing for critical elements and rehabilitation funded by the Queensland State Government. Specific areas of research include: 

  • Mining wastes geochemical and mineralogical characterisation to seek opportunities for critical elements extraction
  • Microbiological characterisation of mining wastes and the application of microorganisms in mining wastes bioleaching
