RESEARCH INTEREST

My research is centred on phytoplankton dynamic, and nutrients biogeochemistry, two key parameters that act together to affect the biogeochemistry of numerous elements including the global carbon cycle and thus the carbon footprint of aquatic systems.

COMMUNITY INVOLVEMENTS

  • Chairing a session on “Trace elements in marine systems: source, cycling and bioavailability” at the 2010 Australian Marine Sciences Association Conference
  • Participation in the design of the Australian new Research Vessel for future studies in Biological and Chemical Oceanography.
  • Co-editor of a special issue of Frontiers in Microbiological Chemistry – a speciality of Frontiers in Microbiology.
  • Associate Editor of the Journal Marine and Freshwater Research.
