Overview

Cassandra is a Research Fellow at QAEHS, joining the group in 2019. She completed her PhD at the University of Birmingham in 2014 where her research focussed on determining how humans are exposed to flame retardants from their indoor environments. Following her PhD she completed a Postdoctoral Fellowship at Environment and Climate Change Canada where she was the principal researcher for the Global Atmospheric Passive Sampling (GAPS) Network, researching chemicals of concern in the atmosphere. Following her Postdoctoral Fellowship she worked for the Oil Sands Monitoring Program in Canada, assisting with facilitating a multi-stakeholder funding program for assessing environmental impact of Oil Sands operations, before returning to Australia in 2019.

At QAEHS she is the project lead investigating human exposure to microplastics and developing new methods for detecting micro and nanoplastics in human matrices. Her other research interests include the impact of tyre road wear particles and the chemical additives they contain on urban water ways, and developing novel biomonitoring methods for assessing human exposure to chemicals of concern (e.g. silicone wristbands and breast implants).

Research Interests

  • Environmental occurrence of microplastics
    Microplastics are one of the biggest pollution challenges the world is currently facing. Yet there is still limited understanding on sources and fate in the environment. Our research group at QAEHS is investigating how micro and nanosized plastics enter the environment, how they are transported through environmental compartments and their long term fate once in the environment. By understanding sources and fate we can implement measure to reduce and remove these pollutants.
  • Non-invasive samplers for human biomonitoring
    We are constantly exposed to a myriad of different chemicals in our everyday lives (the chemical exposome). There is still a lack on understanding on the extent of this exposure and the bioaccumulation of these chemicals within the human body. We are developing non-invasive samplers, coupled with non-target analysis techniques, to determine the human body burden of our chemical exposures. These methods include silicone wristbands and reclaiming medical waste (silicone breast implants) for analysis of exposure and accumulation.
  • Impact of tyre wear and tyre additive chemicals on the environment
    Tyre road wear particles (TRWPs) are formed through every day abrasion of tyres on road surfaces and are now recognised as one of the largest sources of microplastics to the urban environment. Whilst being a significant source of microplastics they also contain a wide range of harmful additive chemicals. Our group is studying the occurrence, fate and impact of TRWPs and the chemicals they contain on the Australian environment with the aim of reducing their concentrations and impact.
  • Human exposure to plastics
    Humans are exposed to microsize and nanosize plastics everyday but there is still little understanding on this exposure, particularly their fate after we are exposed. In collaboration with the Minderoo foundation we are developing robust analytical methods to confidently quantify plastics in human matrices and assess if there is a risk from this exposure.

Available Projects

  • We are continually exposed to a complex mixture of chemical pollutants through several pathways. Our exposures are highly specific, with different patterns of exposure from the different aspects of our lives. Increasing complexity in the chemicals being used and produced makes characterising this exposure increasingly challenging. To address this challenge there is a need for improved and robust biomonitoring methods to understand the complete picture of our exposures which will facilitate effective mitigation strategies against exposure to chemicals of high concern.

    This project will develop and apply polydimethylsiloxane (silicone) as a non-invasive human biomonitoring device to advancing understanding on key and unknown chemical exposures to the Australian population. Using silicone wristbands and donated silicone prostheses (breast implants) chemical exposures in a range of scenarios will be quantified through both target and non-target chemical analysis using chromatographic techniques coupled to mass spectrometry (GC/LC-MS). The successful applicant will have access to a range of archived samplers specific to various exposure scenarios as well as the advanced analytical instrumentation necessary to successfully complete the project.
