Gastrointestinal 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.
