Emilie Gauthier specialises in processing and degradation of polymers, her main interests are in developing natural polymers from sustainable sources and biodegradable.

Originally from France, Emilie Gauthier came to Australia in 2006 to undertake an internship as part of her Masters degree. She commenced working as a Research Assistant at the University of Queensland (UQ) with Professor Pete Halley. With a background in materials science engineering, Emilie joined the CRC-P project team in 2007 to develop photo-degradable films for agriculture. This project was in collaboration with Integrated Packaging, where one of her role was to coordinate large-scale field trials across Australia, New Zealand and Ireland. This 10 years relationship with Integrated Packaging gave her the opportunity to work closely with industry and understand their goals and timeline.

As a key member of the CRC-P, Emilie also contributed as a project CI to the CRC Polymers extension for the photo-degradable films project from 2012 to 2017. Additionally, during 2016, Emilie was part of the team that won the CRC Association Technology Transfer Award, and her role in field trial performance obviously was instrumental to receiving this award.

In order to further pursue her career goals, Emilie embarked in 2012 on a part-time PhD in addition to full-time employment. For her PhD thesis she investigated the effect of different environmental conditions on the degradation rate of agricultural polyethylene films. 

Industry Engagement

  • Duglalunji Aboriginal Corporation (2018 -)
  • CRC for Polymers (2007-2017)
  • Integrated Packaging (2007-2017)

Emilie is strongly engaged in commercialisation activities as she contributed to patent publications while she was a member of the CRC for Polymer. She has now embarked in the spinifex nanocellulose platform, where her role is to develop method with standard protocol to characterise the nanocellulose fibres during the different processing stage. This will enable to ensure consistency in testing and quality control in order to characterise the nanocellulose fibres.
