Peng Du’s route into New Zealand science began well before the research prizes. As an 11-year-old newcomer at Kelston Intermediate, he encountered a different language, unfamiliar classroom customs and classmates who went barefoot. Years later, the Auckland researcher would help develop ways to measure electrical activity in the gut.
His inclusion in the University of Auckland’s 2025 promotions to professor provides a recent milestone in that longer story. It also offers a specific example of a Chinese migrant’s contribution to New Zealand research: work built through local schooling, university training and sustained collaboration with clinicians and engineers.
A school journey before a scientific career
The university’s May 2023 UniNews profile describes Du growing up in Ürümqi and moving to New Zealand with his family in the late 1990s. At Avondale College, he progressed from a lower-stream class to the top stream. His later biomedical engineering studies brought together chemistry, biology and engineering.
These details make the story more useful than a simple list of honours. His entry into research followed a period of adjustment within New Zealand’s education system. They do not establish that every migrant student will have the same experience, but they give that often abstract discussion a recognisable local setting.
Making the gut’s electrical signals visible
In a first-person account for Royal Society Te Apārangi, Du explains how the research team adapted printed-circuit technology to create flexible arrays of electrodes. These allowed researchers to map the movement of electrical signals across the stomach at high resolution.
He places the work within a collective effort. Andrew Pullan helped bring expertise from the heart’s electrical system into gut research; the Auckland clinical mapping team also included Leo Cheng, Greg O’Grady, John Egbuji and John Windsor. Du’s account dates its clinical mapping study at Auckland City Hospital to July 2008.
The aim was to understand how digestive function relates to electrical patterns, and how those patterns can become abnormal. This is research into measurement and disease mechanisms, rather than a claim that a single device can explain every stomach complaint or guarantee a treatment.
Research that crosses institutional boundaries
The university reported in 2023 that the work had contributed to Gastric Alimetry, a wearable system recording gastric bioelectrical activity without invasive access to the stomach. That report described its use in more than 15 hospitals across five countries at the time; those figures should be read as a dated snapshot, not a current deployment count.
Recognition also needs its dates kept straight. Du received the Prime Minister’s 2018 MacDiarmid Emerging Scientist Prize at a ceremony in March 2019. His later professorial promotion belongs to 2025.
The wider Auckland Surgical Engineering Laboratory describes another part of this ecosystem: medical students working alongside engineers to develop and assess devices and interventions. Its academic membership includes Du.
For Chinese New Zealand readers, his career connects several familiar places and experiences with a less visible contribution to public life. The path runs from West Auckland classrooms to interdisciplinary research, where progress depends on shared expertise, patient investigation and the ability to turn difficult biological questions into measurements that others can use.
