Dr Natasha Hungerford is an organic chemist and has extensive experience in natural products chemistry. She is a Senior Research Fellow leading the Natural Toxin group within the Centre for Animal Science, Queensland Alliance for Agricultural and Food Innovation (QAAFI) and is based at the Health and Food Sciences Precinct (Cooper's Plains). She joined QAAFI in 2016 and specialises in natural plant toxins and their impacts on livestock and human health, including food safety and regulations. Collaborative projects with government/industry have spanned mitigation of toxin impacts on cattle, to evaluation of toxins in honey (and health impacts). Subsequent examinations of stingless bee honey serendipitously led to the ground-breaking discovery of the rare sugar trehalulose as a major component of these honeys. Dr Hungerford continues to lead and manage projects to address agricultural industry challenges, including reducing methane gas emissions for a carbon neutral beef industry and international stingless bee honey development.

Dr Hungerford achieved her PhD in 1998, through the UQ School of Chemistry and Molecular Biosciences, and subsequently conducted postdoctoral research in natural products chemistry and in synthetic organic chemistry, at the University of Oxford, Australian National University, The University of Sydney, Griffith University and Memorial Sloan-Kettering Cancer Center.

Biography

Jeffrey Mak (PhD) is an organic chemist at the Institute for Molecular Bioscience. His publications cover a range of disciplines such as biological and medicinal chemistry, total synthesis, and physical organic chemistry. Dr Mak was selected as a Rising Star of Chemistry by the Australian Journal of Chemistry (2022).

Jeffrey Mak was awarded the Harriett Marks Bursary and a UQ University Medal before undertaking doctorate studies in natural product total synthesis with Prof. Craig Williams. This culminated in the first total synthesis of two caged diterpenes, (−)-neovibsanin G and (−)-14-epi-neovibsanin G. Next, he joined Prof. David Fairlie's group at the Institute for Molecular Bioscience. He is currently active in the fields of chemical biology and drug development. He is recognised for his development of ligands that modulate mucosal associated invariant T (MAIT) cells, which are a newly characterised subset of immune cells important in antibacterial defence (Accounts of Chemical Research, 2021). In 2014, he was part of an Australian team that discovered the identity of the ligands that activate MAIT cells, as published in Nature, playing a key role in the chemical synthesis and characterisation of the unstable and structurally unprecedented ligands (Nature Communications, 2017). He was selected as a CAS SciFinder Future Leader by the Chemical Abstract Service (a division of the American Chemical Society, 2017). In 2018, Dr Mak was chief investigator on a UQ Early Career Researcher Grant for developing new drug leads that target MAIT cells. Other recent awards include RSC Twitter Poster Conference (Chemical Biology) 1st Prize (2018), and a CASS Travel Award (2018).

Dr Mak has lectured in the undergraduate course Advanced Organic Chemistry (CHEM3001, 2017-2023). He has also served as a member of the UQ Cultural Inclusion Council, and as an ACS Wikipedia Fellow to systematically improve the chemistry and scientific content on Wikipedia (2018).

Dr Viviene Santiago is a Postdoctoral Research Fellow in the Natural Toxins group within the Centre for Animal Science, Queensland Alliance for Agriculture and Food Innovation (QAAFI) and is based at the Health and Food Sciences Precinct (Coopers Plains). With a robust foundation in organic and analytical chemistry, her research primarily focuses on natural products chemistry from terrestrial, marine, and microbial sources.

Dr Santiago joined QAAFI as a Postdoctoral Research Fellow in 2023. Her current research involves developing a delivery system for bioactive compounds aimed at reducing enteric methane emissions in cattle and exploring atypical sugars in novel foods such as stingless bee honey. Over the years, she has cultivated a keen interest in utilising liquid chromatography-mass spectrometry (LC-MS) and molecular networking techniques to investigate chemical diversity from different sources such as natural toxins in certain plants and atypical sugars in stingless bee honey.

Dr Santiago earned her Ph.D. from The University of Queensland, where her dissertation focused on applying advanced molecular networking techniques, such as the Global Natural Products Social Molecular Networking (GNPS), to explore the chemical diversity of Australian microbes. Her academic journey also includes a Master’s and a Bachelor’s degree in Chemistry from the University of the Philippines – Diliman. These academic experiences have equipped her with a comprehensive understanding of natural products chemistry, enabling her to make significant contributions to both academia and industry.

Dr. Norhasnida Zawawi is an Honorary Senior Fellow at the Queensland Alliance for Agriculture and Food Innovation (QAAFI), University of Queensland, Australia, where she contributed to the discovery of trehalulose, a rare low-GI sugar in stingless bee honey. She is currently Head of the Halal Science Laboratory at the Halal Products Research Institute and Senior Lecturer at Universiti Putra Malaysia (UPM), leading the Halal Healthcare and Wellness Research Programme.

She has played key roles in developing honey standards, including contributions to the FSANZ-approved native bee honey standard (2024), and previously served with the Department of Standards Malaysia and Apimondia Asia. Dr. Zawawi is an Editorial Board Member of the Pertanika Journal of Tropical Agricultural Science and a reviewer for high-impact journals such as Food Chemistry and Journal of Apicultural Research.

With over RM 1 million in research funding, 46 Scopus-indexed publications, and an H-index of 20, her work bridges food science, halal innovation, and bee product research.

Dr. Zawawi’s future research is centred on advancing functional foods and halal-certified bioactive products, with a strong emphasis on native bee honey and plant-based milk alternatives. Her goals include:

• Exploring bioactive compounds and unique compositions of stingless bee honey, plant seed beverages, and other alternative foods to enhance human health.
• Integrating omics technologies to identify molecular markers of efficacy and quality in halal-certified functional foods.
• Promoting sustainable innovation in the halal wellness industry through translational research and commercialisation pathways.
• Expanding global collaborations to support cross-disciplinary research in food science, nutrition, and halal product development.

These goals reflect her commitment to bridging traditional knowledge with cutting-edge science, enhancing public health, and supporting the growth of the native bee honey and halal food industries worldwide.
