Dr Peng Du

BE(Hons) PhD

Profile Image
Senior Research Fellow


Peng Du has a Bachelor of Engineering (Honours) in Biomedical Engineering and a PhD in Bioengineering, both from the University of Auckland.

In 2011 he joined the Gastrointestinal Research Group at the Auckland Bioengineering Institute as a Research Fellow. The focus of his research is on experimental recording and mathematical modelling of gastrointestinal electrophysiology. In particular, he is interested in using experimental data to reinforce multi-scale simulations of gastric electrical activity.

In 2012 Peng won the Vice Chancellor's Prize for Best Doctoral Thesis. Later that year, Peng was awarded a Marsden Fast Start Grant, and a Rutherford Foundation NZ Post-doctoral Fellowship. In 2013, he received a University of Auckland Early Career Excellence Award.

In 2015, he was awarded one of the prestigious Rutherford Discovery Fellowships.


Research | Current

Peng's current research focus is two-fold.

  1. He is investigating the structural-functional relationship of gastrointestinal electrophysiology.
  2. He is trying to apply non-invasive techniques to record gastric electrical activity.
