Gastrointestinal System

Mathematical model of the digestive system

The major functions of the gastrointestinal (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.

The aim of our group is to use computational and mathematical modelling to link cellular and tissue level models to integrate physiological processes and clinical observations at the whole organ and whole body levels. Through this process we are improving our understanding of the GI system in health and disease.

Research assistant opportunities

We seek two motivated candidates for 2-3 month research assistant positions to investigate apsects of gastric slow wave activity and high-resolution mapping techniques. The successful candidates will have the opportunity to work with leading bioengineers and clinicians at the Auckland Bioengineering Institute and international collaborators.

Ideal candidates will have interests in:

  • Experimental physiology
  • Signal and image processing
  • Quantitative analysis, visualisation and data presentation
  • Biomedical device development and electrode design
  • Engineering, and applied mathematics
