Overview
Background
I am a globally recognised leader in lived-living experience led research on substance use, particularly image and performance enhancing drugs (IPEDs). Presently, I am a senior research fellow at The University of Queensland, School of Public Health, funded through an NHMRC Investigator Grant to examine how both individual behaviours and systemic factors, such as stigma and healthcare barriers, shape the risk profiles of people who use IPEDs. I have received >$11 million in funding as Chief Investigator and have authored >200 outputs.
I have strong national and international partnerships. I am the Peer Research Lead and Vice President of the Queensland Injectors Voice for Advocacy and Action (QuIVAA), Research Lead (QLD) for The Loop Australia, QLD Representative for Australian Injecting and Illicit Drug User League (AIVL), a Visiting International Fellow at Swansea University, and one of six members of the Performance Enhancement Task Force for The Enhanced Games.
My award-winning research program triangulates insights from IPED consumers and health professionals to address critical policy and service gaps. This has led to pioneering initiatives such as the world's first steroid checking trial and full program, which was awarded Harm Reduction Program of the Year (AIVL, 2024). I also founded Steroid QNECT, Australia's only peer-led steroid education program, now informing national and international health enhancement strategies related to IPEDs. I have received several competitive awards, including the AIVL Peer Researcher Recognition Award (2024), the APSAD Kyp Kypri Early Career Researcher Award 2024, and more recently the QMHC Emerging Leader Award 2026 and AIPS Tall Poppy Science Award (QLD) 2026.
I am the Section Editor for Human Enhancement Drugs at the Harm Reduction Journal, and sit the Editorial Boards of Performance Enhancement & Health, Drugs: Education, Prevention, and Policy, and Addiction Research & Theory.

Enhancement Drugs
Research on anabolic-androgenic steroids (AAS), peptides and other image and performance enhancing drugs (IPEDs), including patterns of use, motivations, harms and changing drug markets. This work examines how IPED use is shaped by fitness cultures, social networks, digital environments and broader processes of drug normalisation.
Research impacts
ROIDCheck: transforming IPED harm reduction through drug checking
ROIDCheck is the world’s first full-service AAS drug checking program, combining laboratory analysis with personalised results, peer-delivered harm reduction and community education. I led its development through a multidisciplinary team spanning 10 partner organisations and ~20 collaborators, integrating laboratory science, digital technologies and lived-living experience into a new model of IPED harm reduction. A lived-living experience advisory group (n=5) guided intervention design, engagement and dissemination.
The 2024 trial established an international benchmark for IPED harm reduction and was recognised as Harm Reduction Program of the Year (2024) by the Australian Illicit and Injecting Drug Users League.
Between 2024–2025, my team tested more than 300 IPED samples, generating real-time market intelligence, health alerts and guidance for peer organisations and health services. We identified substantial market instability: 15.2% of samples contained unexpected or mislabelled compounds, while only 9.6% of quantifiable samples were accurately dosed.
Importantly, ROIDCheck demonstrated measurable behavioural impact. Among 50 consumers submitting 212 samples, those receiving personalised drug-checking results and a peer-delivered health intervention were significantly more likely to report modifying their AAS use than those accessing aggregated community results (91.3% vs 46.3%). Changes included reconsidering compounds, adjusting doses, changing sources and intending to test products before use.
ROIDCheck is now forming the foundation for national expansion, translating research evidence into a scalable model of community-led harm reduction.
Steroid QNECT: embedding lived-living experience into healthcare and harm reduction
Steroid QNECT is a peer-led, confidential support and education program that I co-developed and lead through QuIVAA. It is Australia’s only dedicated IPED peer-led service, embedding lived-living experience in governance, design and delivery.
Since 2025, Steroid QNECT has:
- Supported 3,000+ people through confidential advice, risk assessment, education and referral;
- Trained 5,000+ health professionals across 30+ services, strengthening workforce capacity to respond to IPED use; and
- Delivered 30+ community events, including gym outreach, youth seminars, parent and carer sessions and festival engagement.
The program has expanded beyond individual support to influence health systems and public health practice. Steroid QNECT is now embedded within Queensland and New South Wales Department of Health-funded services and collaborates with organisations across Australia, including QuIHN, Harm Reduction Victoria, NSW Users and AIDS Association and Peer-Based Harm Reduction WA.
Its knowledge translation activities have also achieved substantial reach. Co-developed digital resources and training materials have generated more than 300,000 visits across 60 countries, extending evidence and peer expertise beyond traditional health services and into the online communities where IPED information is increasingly exchanged.
