Career Summary
Biography
I seek to understand the fate and behaviour of chemical contaminants in soils after their release and how humans, plants, and ecological organisms can be exposed to these contaminants, as well as understand the potential health risks from such exposures, including how to minimise and manage those risks.
My current research seeks to understand the fate and behaviour, particularly sorption (retention) and desorption (release), of PFAS in soils. It is my hope my research will help minimise the uncertainty associated with understanding the real behaviour of PFAS in different soils. I have experience investigating the bioaccessibilty of highly sequestered polycyclic aromatic hydrocarbon residues in long-term contaminated soils, and evaluated associated risks to human and ecological health using solvent extractions, earthworm exposure, and in vitro bioaccessibility experiments. I have also worked with C-14 respirometric assays to study the fate of PAHs during plant-assisted biodegradation.
Open to discussing potential collaboration and supervision opportunities on exciting and impactFULL projects.

International Workshop on Science Diplomacy and Innovation Diplomacy I was one of the 40 researchers (and 2 from Australia) selected through a competitive process from a pool of over 1000 global applicants by the Advanced School of Science and Innovation Diplomacy Sao Paulo to attend the 10-day international workshop on science and innovation diplomacy at the University of Sao Paulo, Brazil. As a result of my participation at the workshop, I have an understanding and am developing an international network in the field of science and innovation diplomacy, valuable for successful scientific cooperation and collaborations in Australia and beyond. |
