Once food is ingested, the stomach serves as a reservoir and continues to break down the food into smaller particles until they are small enough to progress into the small intestine. The rate at which different types of foods break down is of great interest to food technologists, pharmaceuticals and bioengineers. Our research group has developed methods to image the contraction of the stomach in an MRI and have used these images to develop subject-specific computational fluid dynamics (CFD) simulations to improve our understanding of how stomach contractions mix and break down food. 

In the next phase of this research, we seek to use MRI to track the breakdown of food contents over time, and the rate at which food empties from the stomach in both normal subjects and patients with chronic indigestion. New CFD simulations, such as with multi-phase flow interactions, will be developed to help interpret the stomach MRI data.

Desired Skills

Bachelor’s or Master’s degree in Engineering, Physics or equivalent. Experience with mathematical modelling, data analytics, image processing, computational fluid dynamics. Some familiarity with MATLAB, Python, and CFD simulations be desirable.

The Auckland Bioengineering Institute - breaking boundaries in bioengineering for more than 20 years

At the Auckland Bioengineering Institute (ABI), we apply engineering and technical innovation to advancing medical care, human capability, and understanding of human physiology. Our team of world-renowned researchers are working on everything from artificial intelligence avatars, to implantable devices, to digital models of the human body. Our focus on research excellence and commercialisation adds value to society and to the global economy.

Our research makes a real difference in the world. We’ve designed sensors to diagnose stomach disease without needing invasive surgery; developed a tiny wireless implantable device to measure brain pressure and save the lives of children with hydrocephalus; and we lead the world in building digital models of the human body which will enhance personalised medicine approaches for improved diagnosis and treatment.

Join our team of researchers for a postgraduate degree and together we can make a difference. Our graduates are amongst the most employable in the world - many either continue their career in research, find employment with industry leaders such as Rocket Lab or Fisher & Paykel, or launch their own startup companies.

Our students come from over 50 different countries and a wide range of backgrounds and disciplines, including Engineering, Medicine, Mathematics and Science.
