Research interests + projects

Biomonitoring: Using metagenomics to monitor bioprocesses for process optimization and control, and impacted environments for microbial response, resilience and recovery to disturbances.

Bioprocessing: Developing nature-based technologies following the principles of zero waste and a circular economy within the natural resource sectors of mining, forestry and agri-food industries.

Biomining: Recover nutrients and strategic metals, such as selenium, zinc and copper, from mine wastes using microbially mediated approaches.
