The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Over 80 million people have chronic constipation. It affects over 1/5 older people and is a major problem in aged-care. We have found that a painless method of electrical stimulation across the abdomen can overcome chronic constipation in children and adults. We will test the method to see what types of constipation it can help, including constipation caused by pain-medication and irritable bowel syndrome. This treatment is given at home and could improve life for many people around the world.
Translational Studies Of Novel Methods For The Assessment Of Gastrointestinal Motility.

Summary
Swallowing has complex physiology and swallowing problems (dysphagia) result in poor nutrition and death due to complications of aspiration. A/Prof Omari has invented a new method to assess swallowing function. The studies proposed will change how dysphagia is diagnosed and managed. The research follows three streams: (A) studies in large patient cohorts in whom a better diagnosis is needed (e.g. stroke), (B) studies of therapies and interventions and (C) studies of swallowing biomechanics.
Understanding And Preventing Inflammatory Pathology Of The Gut

Summary
My research focuses on how inflammation caused by bacteria or organ malfunction can lead to severe disease like cancer in the gastrointestinal tract. Our aim is to better understand diseases like gastric cancer and inflammatory bowel disease, and to develop new ways to detect them and prevent them progressing.
Bacterial pathogens are a major cause of illness and death, producing diseases ranging from acute infections to cancer. However, not all infected individuals will succumb to these pathologies. What factors dictate which individuals develop these diseases is an important complex question. The core focus of my research is the identification and characterisation of novel host factors that are involved in resistance or susceptibility to bacterial-associated diseases of the gastrointestinal tract.
The Molecular Basis By Which IL-6 Family Cytokines And Pathogen Recognition Receptors Promote Inflammation-associated Stomach And Lung Cancer

Summary
Lung and stomach cancer are the 2 most lethal cancers world-wide, and represent a growing number of cancers associated with chronic inflammation. However, the genes which trigger inflammation and then promote cancer in certain people remain largely unknown. Using mouse models for these inflammation-associated cancers, together with clinical specimens, our aim is to identify specific genes of the immune system which trigger chronic inflammatory responses that lead to cancer.
Gut motility requires enteric neurons, which are located in the gut wall. During development, enteric neurons arise from precursors in the brain that migrate into the intestine. Failure of enteric neuron precursors to migrate and differentiate normally results in pediatric motility disorders. The aim of this research is to identify the mechanisms controlling the development of enteric neurons so that therapies can be developed for pediatric motility disorders.
