Cassandra is a Senior 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).

Professor Kevin Thomas is Director of the Queensland Alliance for Environmental Health Sciences (QAEHS). Kevin is an environmental health scientist with a particular interest in understanding the environmental exposures associated with contaminants of emerging concern (CECs) with the goal of protecting environmental and human health. Kevin also leads the Minderoo Centre- Plastics and Human Health at UQ and is Deputy-Director of the Australian Research Council Industrial Transformation Training Centre for Hyphenated Analytical Separation Technologies (HyTech).

His current research is focused on understanding human exposure to plastics pollution and developing mass spectrometric analytical methods for characterizing plastics and other CECs, assessing community-wide health status through analysing wastewater (wastewater-based epidemiology) and establishing alternative approaches to exposure monitoring, for example explanted silicone prostheses and wristbands.

Author of over 300 peer-reviewed papers and Associate Editor for the journal Science of the Total Environment, Kevin is a strong collaborative researcher having founded the international SCORE network on sewer biomarker analysis for community health assessment (see www.score-network.eu) and together with colleagues has recently launched InSpectra- A platform for identifying emerging chemical threats.

Dr Ben Tscharke is an analytical chemist with a keen interest in quantifying analytes in environmental samples. Ben is currently a Senior Research Fellow at the University of Queensland research institute, Queensland Alliance for Environmental Health Sciences (QAEHS), joining in February 2017 after graduating his PhD from the University of South Australia the previous year. His key focus at QAEHS involves the wastewater based epidemiological approach to determine community consumption and exposure to a range of illicit drugs, pharmaceuticals and personal care products. He leads the Australian Criminal Intelligence Commission's National Wastewater Drug Monitoring program at UQ, which collaborates with the University of South Australia (https://www.acic.gov.au/publications/intelligence-products/national-wastewater-drug-monitoring-program-report).

Associate Professor Ryan Turner is the Director of the Reef Catchments Science Partnership at the University of Queensland (a partnership with the Department of the Environment, Tourism, Science and Innovation). Ryan was previously the Department's Principal Scientist for Water Quality and Investigations and held an Adjunct Associate Professor role at Queensland University of Technology in the Managing for Resilient Landscapes, Institute for Future Environments. For 14 years, Ryan managed multimillion-dollar water quality monitoring programs assessing the impacts of sediments, nutrients, and pesticides in numerous catchments along the Queensland coast discharging to the Great Barrier Reef and Moreton Bay. Ryan has been on several steering committees and technical advisory panels, such as the Great Barrier Reef Foundations Technical Advisory Panel. He has published extensively (>80 papers and reports) and led several Queensland Government – Academic collaborative research projects. Ryan previously supervised analytical chemistry and microbiology laboratories in the private and public sectors. Ryan has developed numerous methodologies and standard operating procedures for analytical and monitoring techniques (water quality, sediments and soils). Ryan’s passion for the future of water security is what keeps him striving forward.

Research on Unusual Molecules and Reactive Intermediates: Synthesis and Reaction Mechanism. Heterocyclic chemistry. Pyrolysis reactions. Photochemistry

Research in the Wentrup group is concerned with the discovery of novel types of molecules with new and unusual bonding patterns. Such molecules are mostly highly reactive, and special methods are required both for their generation and for their detection. The group has developed these methods over many years and acquired world-class equipment for these purposes, including flash vacuum thermolysis apparatus, cryostats for matrix isolation of reaction products at cryogenic temperatures (down to 7 K), matrix and solution photochemistry equipment, infrared, UV and mass spectrometers, as well as modern computational facilities.

This research has resulted in the synthesis and characterization of many novel compounds, including extended cumulenes of the types RN=C=C=C=X, which themselves are used in the synthesis of many novel types of molecules, some of them of potential pharmaceutical interest (quinolone antibiotics; diazepines).

The research group has a world reputation in the field of carbene and nitrene chemistry, involving reactive intermediates with sextet carbon or nitrogen. These species are also very useful in synthesis, for example in the preparation of diazepines and diazepinones, a family of pharmaceutically interesting compounds. Numerous mechanistic studies and synthetic applications of ketenes have been carried out in our group.

Active collaborations are ongoing with scientists in Australia (UQ and CSIRO), China (Suzhou), France (Pau), Germany (Oldenburg), Japan (Hiroshima), Spain (Donostia - San Sebastian), and Portugal (Coimbra).
