    Associate Professor Melissa Thomas

    Biosecurity Scientist

    About me

    Melissa Thomas is a Biosecurity Scientist with the Harry Butler Institute at Murdoch University.  She leads projects that translate novel research findings into management solutions to reduce biosecurity risk from entering Australia, and to improve and automate detection of non-indigenous species already established in Australia.  Melissa works predominantly on terrestrial invertebrates, but also has a range of research projects that investigate new detection or repellent methodologies for vertebrates pests. Her projects are founded on strong links with industry

The Biosecurity team at Chevron won this award for our operational excellence in evaluating environmental performance and seeking continuous improvement.

    2014: Gorgon Team Award – In recognition of teamwork to (1) develop a process for defining and amending weed hygiene zones and then (2) successfully implementing the procedure. This work required aligning Barrow Island stakeholders. Success of this program minimized costs and ensured a standard and transparent process for Chevron Australia.
