Emeritus Professor Grant Morahan, Professor of Diabetes Research, University of Western Australia Centre for Medical Research (affiliated with the Harry Perkins Institute of Medical Research), Perth, Australia & Honorary Professor, Baker Department of Cardiometabolic Health, University of Melbourne, Australia
RESEARCHER PROFILE
Filmed in Perth, Australia | December 2025
Professor Morahan invented the term “Systems Genetics” for the science field that examines how genetic variants can affect whole networks of genes and whole systems; there are now several laboratories and institutes of systems genetics around the world. He also developed the next-generation genetic resource, The Gene Mine, the most powerful of its type in the world, used globally in rapid mapping and identification of genes. Collaborators nationally and internationally have tested The Gene Mine for traits and diseases in which they specialise.
As a member of the Steering Committee of the Type 1 Diabetes Genetics Consortium, he worked to design the global study recruiting and characterising T1D genetics, which resulted in identification of over 40 T1D risk genes. The culmination of this program, for which Prof Morahan was PI of the Asia-Pacific Network, was published in Nature Genetics (41:703-707) and has been cited 1579 times.
Currently, he is a member of the Steering Committee of the Environmental Determinants of Islet Autoimmunity (ENDIA) Study, the only study in the world investigating T1D families to follow at-risk babies from pregnancy through childhood. Completing recruitment in 2020, the study already has 40 publications.
His latest discovery involves next-generation algorithms that are able to predict whether a person will be genetically high/low risk of developing a number of complex genetic diseases. Professor Morahan is working toward commercialising these genetic tests so they can benefit the public and the healthcare system.
During his career, Prof Morahan has supervised 23 postgraduate students and mentored nine postdoctoral positions. Since 2003, Prof Morahan has applied for and received close to $20 million in research funds, both nationally and internationally. He has 299 academic publications, 17,0744 citations and has an h-index of 60.

Neuroscience, neuropharmacology and exercise science
Dr Jacob Thorstensen is an early-career Assistant Professor in Neuroscience and Physiology in the Faculty of Health Sciences & Medicine at Bond University. He is also an honorary research fellow in The School of Biomedical Sciences at The University of Queensland. His work has unveiled several new neuroscientific mechanisms which have future applications for movement disorders.

Life-changing donor milk for preterm babies
Dr Laura Klein is National Milk Research Leader at Australian Red Cross Lifeblood. Australian Red Cross Lifeblood is funded by Australian governments to provide life-giving blood, plasma, and transplantation and biological products.
Dr Klein works with clinicians and researchers across Australia to understand how donated breast milk can be used to improve outcomes for vulnerable babies. She’s passionate about generating evidence to improve the products and services that milk banks provide to donors and the families who receive donated breast milk.

Inner ear organoids for the study of human hearing and balance
Dr Jackie Ogier is an auditory neuroscientist, with a research focus on the molecular biology of hair cells, the specialised sensory receptors in the ear that detect sound and balance. She is a postdoctoral research fellow in the laboratory of A/Prof Bryony Nayagam, supported by a prestigious Passe and Williams foundation fellowship.
Dr Ogier’s experience broadly spans the genetics of hearing loss, disease modelling, micro dissection, primary cell culture, stem cell culture, organoids, and proteomics. Overall, she aims to generate knowledge of hearing and vestibular sensory biology.
