Nepean Clinical School research

Medicine and surgery research in over fifteen disciplines
With connections across university research centres, and research groups in a range of medical disciplines, we aim to bring the latest medical research and treatments to Nepean.

Medical research is a major part of Nepean Clinical School's activities. Our research is particularly strong in the areas of critical care medicine, endocrinology, gastroenterology, geriatric medicine, haematology, perinatal medicine and surgery.   

Many postgraduate research students undertake higher degree research in our dedicated research laboratories and facilities, under the supervision of our leading academics and clinicians. If you are interested in undertaking research with us, please contact the relevant project lead, or learn more about postgraduate research in medicine and health.

Research centres and institutes

As part of the Brain and Mind Centre network, Nepean Clinical School shares the mission to transform brain and mind health with world-leading research.

The Brain and Mind Centre Nepean plans to bridge the gap in knowledge and services between Sydney’s western and eastern suburbs by developing numerous cross-campus, multidisciplinary, collaborative research and education projects in neuroscience and mental health.

As part of the Charles Perkins Centre network, Nepean Clinical School shares the mission to ease the burden of obesity, diabetes and cardiovascular disease by enabling collaborative interdisciplinary research and education.

The Charles Perkins Centre Nepean was launched to meet the demand for evidence-based research that could be translated directly into life-changing outcomes for residents of greater western Sydney.

Our research groups

Our groups conduct research across a range of disciplines in medicine and surgery.

The Department of Intensive Care Medicine has a large and active research program. The three main areas of research that drive our program are:

  • the use of genomics, with the Nepean Genomics Unit researching molecular biological patient responses in sepsis, with a particular focus on respiratory viral infections using transcriptomics of circulating white cells.
  • the Nepean Intensive Care Unit has gained an international reputation in the field of critical care echocardiography research, which runs parallel to an extensive educational program nationally, Asia and Europe.
  • for over two decades, the department has participated in multiple large multicentre studies on critically ill patients, many of these being hallmark studies in the field of intensive care medicine.

Non-alcoholic steatohepatitis

Did you know that people with increased fat in their liver due to non-alcoholic fatty liver disease (NAFLD) can suffer from cardiovascular related death before suffering from liver related death?

NAFLD is the most common type of liver disease, affecting an estimated 5.5 million Australians, including 40% of all adults aged 50 years and above.

The research endeavours of the Haematology Group are focused towards a better understanding of chronic lymphocytic leukaemia (CLL) through genetic and epigenetic studies of familial CLL and by studying the protein interactions initiated by activation of the B-cell receptor and the influence of the CLL microenvironment on these protein networks.

Our group also has a strong interest in the biology of the ATP-gated, cation-selective, P2X7 receptor and its significance to human infectious, malignant and autoimmune diseases with a particular focus on single nucleotide polymorphisms and splice isoforms of P2X7 and their role in inflammation.

Current Project:

Improving the outcomes of chemotherapy treatment for cancer by reducing damage to normal cells. Learn more

Our research interests include:

  • zoonotic and intracellular pathogens, especially Chlamydia psittaci, Staphylococcal blood stream infections and prosthetic joint infection
  • combination antibiotic treatment
  • HIV and HCV co-infection

The Nepean Medical Imaging Group aims to, through education and research, promote the appropriate use of radiology and nuclear medicine/PET in modern investigation and management of patients. This specialty is at the forefront of new technologies, which requires in-depth knowledge of basic sciences (particularly anatomy, physics and pathology) that is fundamental to the study of medicine.

Our research includes:

  • radiology and nuclear medicine/PET
  • informatics
  • interventional radiological procedures
  • radionuclide therapies and cardiac imaging
  • CT coronary angiogram.

We are a collection of like-minded healthcare professionals and researchers with an interest in better understanding metabolic health and disease. Specific conditions that are a focus for our group include:

  • those of overweight and obesity
  • pre-diabetes and diabetes
  • non-alcoholic fatty liver disease
  • dyslipidaemia and cardiovascular risk.

Our research aims to both understand the development of, and manage, these conditions and their associated diseases. 

Current projects include:

  • PreBabe is a world-first clinical trial exploring how losing weight prior to pregnancy can improtve the long-term health of mothers and babies. Learn more
  • Fibre supplement and Ginseng for weight loss and blood sugar control. Learn more
  • Randomised controlled trial to investigate the efficacy of dexamphetamine compared to placebo for treating obesity complicated by obstructive sleep apnoea

Obesity study

Obesity is a major problem for our local population in Penrith. Access to specialised treatment is often limited to those with the most severe disease, neglecting people who are only slightly overweight or obese. People who are overweight are more likely to have obstructive sleep apnoea, a condition associated with snoring and pauses in breathing while asleep.

A program to help such people to get their weight under control before they develop more severe obesity could be very worthwhile.

We have a research study testing a 6 month treatment program for establishing a healthy diet and lifestyle changes to help people lose weight. In this study half of the participants will also be given dexamphetamine, while the other half are given placebo (inactive pills). Dexamphetamine reduces the appetite and also increases motivation. The increase in energy and motivation may help people to establish a new lifestyle with more exercise which may help them to keep control of their weight.
