About our group

We utilise a combination of experimental measurements and mathematical modelling techniques to provide an integrated understanding of gastrointestinal function in both health and disease.

Researchers are developing tools and techniques to improve our understanding of the gastrointestinal (GI) system.

The major functions of the GI system include ingestion, digestion, absorption, excretion and protection. These important and sophisticated functions are coordinated via a number of different organs and over a range of length and time scales.

Research questions

  • Can we help to improve our understanding of how the GI system processes food?

We have developed mathematical models of the stomach and small intestine (a virtual gut), to help understand the breakdown of food and to test hypotheses. Our models explain the electrophysiological processes from cellular to organ level occurring during the digestion. They also help to define and visualise the effects of structural and functional abnormalities in the GI organs on the digestion.

  • Can we develop new tools to accurately diagnose the electrical dysfunction associated with various forms of severe indigestion?

We have developed new devices and techniques for high-resolution mapping of gut electrophysiology, including automated signal processing and model-based analysis and visualisation software. We are now in the exciting phase of applying all of these techniques to clinical practice.

  • Can we develop new therapies to help treat GI electrical dysfunction disorders?

We are currently testing and refining new medical devices and therapeutic techniques that have the potential to help correct abnormal GI function. Our devices and techniques are tested through in-vivo experiments and assessed by post-processing analyses and modelling.
