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.

Faecal Microbiota Transplantation And Other Novel Therapeutic Microbial Manipulation Strategies In Inflammatory Bowel Disease
Funder
National Health and Medical Research Council
Funding Amount
$645,205.00
Summary
There is growing interest in the role of microbial-based strategies including faecal microbiota transplantation (FMT) for the treatment of inflammatory bowel disease. This project will develop such strategies into valid treatment options through a combination of clinical & basic science work including (1) characterising viral & fungal factors of importance, (2) evaluation of novel orally-delivered formulations of FMT, and (3) development of better defined, more reproducible microbial treatments.
Understanding The Interplay Between ER Stress And Inflammation
Funder
National Health and Medical Research Council
Funding Amount
$560,918.00
Summary
Chronic inflammatory diseases in the gut and lung affect hundreds of thousands of Australians. We have identified how inflammation causes a type of stress resulting in abnormal protein synthesis in the cells which make the barrier to microbes. Following an infection this process might be the trigger for chronic unresolving inflammatory disease. The further understanding of this process we seek in this project is likely to lead new approaches to treat common inflammatory diseases.
REMEDYING THE NEGLECT OF THE MOST COMMON COMPLICATION OF INFLAMMATORY BOWEL DISEASE: INTESTINAL STRICTURES.
Funder
National Health and Medical Research Council
Funding Amount
$123,368.00
Summary
Inflammatory bowel disease is a significant cause of debility in the Australian community. Some patients develop narrowing of the bowel which can cause intestinal blockages and require surgery. My research in this area will identify predictors of severe disease, allowing doctors to individualise treatment plans for each patient. I will also work to determine the best model of medical treatment and investigate new techniques which have the potential to avoid surgery.
Stricture Definition And Treatment (STRIDENT) Studies: New Diagnostic And Treatment Modalities For Inflammatory Bowel Disease Strictures
Funder
National Health and Medical Research Council
Funding Amount
$124,676.00
Summary
Inflammatory bowel disease (IBD), which includes Crohn disease and Ulcerative colitis, is becoming increasingly common in Australia. IBD strictures, which are a narrowing of bowel wall as a result of inflammation, can cause obstruction or blockage of food and liquid contents in the bowel. This results in significant patient morbidity and disease burden. Our research will aim to characterise strictures in IBD and investigate novel medical treatments to significantly improve outcomes in IBD.
Isolation And Pre-clinical Evaluation Of Small Molecule Anti-inflammatory Compounds From Hookworms
Funder
National Health and Medical Research Council
Funding Amount
$320,891.00
Summary
This project will harness the unique ability of hookworm small molecules (<10 kDa) to modulate inflammation, and exploit these properties to develop novel modalities to treat inflammatory bowel diseases, using millennia of host-parasite coevolution as a guide. The excretory/secretory and somatic extracts will be assessed for their anti-inflammatory properties using TNBS mouse model. Compounds will be separated using HPLC and identified using MS and NMR spectroscopy.
Muc1 Regulation Of The NLRP3 Inflammasome In The Gastrointestinal Tract
Funder
National Health and Medical Research Council
Funding Amount
$444,351.00
Summary
The mucin Muc1 is an important part of the barrier against infection in the gut, and appears to protect against development of bacterial inflammatory disease. We have identified that Muc1 suppresses activation of the inflammasome (a mechanism by which pathogens cause inflammation). We will now examine how Muc1 does this and explore the importance of this effect on inflammatory disease in the intestine. This may identify novel approaches for protecting against gastric and colorectal cancer.
Integrated Clinical And Scientific Studies In Post-Operative Crohn’s Disease
Funder
National Health and Medical Research Council
Funding Amount
$71,606.00
Summary
Crohn’s disease is a chronic inflammatory bowel condition; the incidence in Australia is now amongst the highest in the world. Most patients require repeated invasive bowel surgeries when disease recurs. Using data from a past clinical trial comparing preventive treatments for recurrence; genetic, immunological and microbiological testing will be done on existing patient samples. This extensive data set will be analysed using systems biology methods to identify the cause of Crohn’s disease.
Interferon Epsilon As A Novel Regulator Of Host-bacterial Interaction In Homeostasis, Infection And Inflammation
Funder
National Health and Medical Research Council
Funding Amount
$843,088.00
Summary
Gut infections are a leading cause of death worldwide and healthcare use in Australia. Inflammatory bowel disease (IBD) is incurable and affects 1/200 young Australians. Type I interferons (T1IFNs) are important to control gut infections and IBD by interacting with particular bacterial species in the gut. We discovered one T1IFN, IFNε, in human gut. It protects against models of IBD in mice. We will use mouse and human samples to find bacterial or interferon treatments for infections and/or IBD.
Understanding And Preventing Inflammatory Pathology Of The Gut
Funder
National Health and Medical Research Council
Funding Amount
$727,758.00
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.
Neuroimmune Interactions In Functional And Organic Gastrointestinal Diseases
Funder
National Health and Medical Research Council
Funding Amount
$419,180.00
Summary
Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD) are chronic, incurable diseases of the lower gastrointestinal tract with unknown causes and poor treatment options. Both the immune and nervous systems are altered in GI disease, but have traditionally been studied in isolation. My research investigates how the neuro-immune axis is altered in these diseases, using animal models and human tissue samples to identify novel treatment options for these debilitating diseases.
