Overview
Background
Professor Kevin Thomas is an internationally recognised environmental health scientist whose research over three decades has focused on a fundamental challenge: how can we identify, measure and understand the environmental exposures that matter for human and ecosystem health?
His research has pioneered new approaches to measuring environmental exposure, from environmental contaminants and complex mixtures to wastewater-based epidemiology, plastics and human health. He pioneered wastewater-based epidemiology as a population-level approach to monitoring community health and behaviour, and has advanced the measurement of micro- and nanoplastics, plastic-associated chemicals, PFAS and other contaminants of emerging concern.
A central focus of his research is making previously invisible exposures measurable. He combines high-resolution mass spectrometry, non-target analysis and advanced approaches to chemical and polymer characterisation to identify and quantify known and previously unrecognised exposures across environmental, population and human matrices.
His current research focuses on the human chemical and particulate exposome—integrating measurements of chemicals, plastics and other environmental stressors with exposure and health data to understand how complex mixtures of environmental exposures affect human health.
Professor Thomas is Director of the Queensland Alliance for Environmental Health Sciences (QAEHS) at The University of Queensland and Director of the Minderoo Centre for Plastics and Human Health. He is also Deputy Director and Queensland Node Leader of the ARC Industrial Transformation Training Centre for Hyphenated Analytical Separation Technologies (HyTech), and is affiliated with the ARC Training Centre for Bioplastics and Biocomposites and the Centre for Marine Science.
His research programme spans four interconnected areas:
Plastics and human health. Developing analytical approaches to identify and quantify micro- and nanoplastics and associated chemicals in environmental and human matrices, and to understand human exposure and potential health effects.
Emerging contaminants and exposomics. Developing high-resolution mass spectrometric and non-target approaches to identify known and previously unknown chemical exposures, including PFAS and other persistent and mobile contaminants.
Wastewater-based epidemiology. Using wastewater as a population-level biological sample to monitor community health, drug and tobacco use, emerging chemical threats and other indicators of population behaviour and health.
Antimicrobial resistance and environmental health. Identifying chemical and biological drivers of antimicrobial resistance in environmental mixtures, and developing approaches to understand their sources, exposure pathways and risks.
Professor Thomas has authored more than 400 pper-reviewed publications and has supervised researchers across environmental chemistry, analytical science, wastewater epidemiology, plastics and human exposure. His research brings together analytical science, environmental health and population-level measurement, with extensive collaboration across government, industry and international research organisations.
Across his research, a consistent focus has been making previously invisible environmental exposures measurable. This has taken his work from known contaminants to complex mixtures, population-level measurements and, increasingly, the chemical and particulate exposome of humans.
