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.

Visceral pain and the gut-brain axis
Professor Stuart Brierley is Director of the Visceral Pain Research Group, Director of the Hopwood Centre for Neurobiology, and Theme co-Leader of Lifelong Health at the South Australian Health and Medical Research Institute (SAHMRI).
Prof Brierley is an international expert on the ‘gut-brain axis’ and chronic visceral pain mechanisms. Current investigations are on a individual cell type called the enterochromaffin cell, and it helps signal pain and anxiety from the gastrointestinal tract to the brain.

Personalised approaches to lung therapy
Dr. Adams’ research focus is on lung cancer, which is the deadliest of all cancers worldwide. He is working towards developing personalised approaches to pinpoint a therapy that is going to be most effective for the person with that disease. Dr. Adams’ research is focusing on chemotherapy and targeted therapy, and he is trying to identify upfront which of those tumours are likely to be resistant to the therapy. He then identifies strategies that will resensitize or increase the sensitivity of the tumour to the standard of care that is targeted therapy or chemotherapy.

CASE STUDY: Transforming surgical waitlist into a ‘preparation list’
The DIAMONDS initiative aims to transform the surgical waitlist into a “preparation list,” enabling healthcare professionals to optimise patient care in the months leading up to elective surgery starting at pre-admission phase.
Patients are will be able to complete pre-admission forms online, receive timely updates, and access educational resources to ensure thorough preparation. This will allow staff to spend more time with patients.
