Professor Bryony James
BEng(Hons) Bath, PhD, MRSNZ
I received my undergraduate degree in Materials Science and Engineering at the University of Bath, England in 1993 and my PhD in Materials Engineering at the University of Auckland in 1998.
I am currently a Professor in the Department of Chemical and Materials Engineering with a research and teaching focus on Materials Science.
Research | Current
I am a materials engineer who has strayed from the true path of metals, plastics and ceramics and now I study food. My research is rooted in traditional materials science approaches, with particular emphasis on the characterisation of structure, and the impact of food structure on food properties and oral processing.
As food structure is altered by chewing so too chewing is influenced by food structure, and as we spiral towards the gullet things become increasingly complex. It’s this challenge that currently puts pennies in my shoes and drives my research programme in food texture and its impact on satiation. I also have ongoing projects linking structure and rheology of chocolate to its oral and functional properties, and the impact of ageing on chewing ability and the perception of texture. In conjunction with Pernod Ricard Winemakers NZ I have previously investigated novel ways of removing proteins from wine, and I have worked with Fonterra examining the impact of structure on the functional properties of dairy products; thus achieving the enviable position of “chief cheese and wine” researcher in the Faculty of Engineering.
