Luke Williams is a proud Gumbaynggirr man of northern NSW. Luke’s research primarily focuses on the traditional uses of native Australian plants with an empathises on understanding how traditionally used food plants can contribute to our modern food systems. This includes the promotion of traditional foods in Indigenous communities to improve food security and cultural wellbeing, through to supporting Indigenous businesses to lead the bush food industry, so that the nutritional and environmental benefits attributed to native plants can be enjoyed by all Australians.

Luke’s PhD looked at the dietary safety assessment of Australian native foods. He continues this line of research today where he takes a mixed method approach. This includes working with Traditional Custodians to understand their history of use with a particular plant, and then supporting consumer safety through the generation of quantitative data, such as the measurement of toxicological endpoints and various chemical analyses.

Luke sees the growing native foods industry as a culturally appropriate economic opportunity for Indigenous Peoples. However, he also understands, that if these foods are to be made available to the public, then there is a need to ensure that they are safe for general consumption.

I am a cognitive neuroscientist with a research focus on the neural basis of language. My research is focused on three related questions:

1. How is language processed in the brain?
2. How does brain damage affect language processing in individuals with aphasia, i.e. acquired language disorders?
3. What brain mechanisms support the recovery of language processing in people with aphasia who improve over time?

To address these questions, my lab studies individuals with aphasia, as well as healthy participants with normal language, using a range of state-of-the-art functional and structural neuroimaging techniques. We combine our multimodal imaging approach with comprehensive language assessments designed to quantify deficits in different components of the language processing system, such as syntactic structure, word meanings, and the selection and assembly of speech sounds.

Helen has over 30 years’ experience as a clinician (orthoptist) and an innovative educator. She was the Academic Lead Assessment in the Academy for Medical Education from mid 2017 to March 2024. Helen’s expertise has been built on a career spanning clinical practice in rural and urban settings fuelling a passion for learning from her early mentor, the late Prof Fred Hollows. Her career in higher education has spanned several roles including lecturing and reforming the orthoptics curriculum, leading elearning projects across five health facilities at the University of Sydney before moving to lead academic development at Charles Darwin University. She has worked in three medical schools (University of Sydney, Flinders University and the University of Queensland) inspiring educators to enhance clinical skills teaching, developing clinical supervisors in Northern Australia and most recently leading assessment design for the new Doctor of Medicine program at University of Queensland. She has received multiple teaching and learning awards at University of Sydney (2003, 2004), Flinders University (2016) and the Australian Awards for University Teaching: Citation for Outstanding Contributions to Student Learning (2017).
