About

Dr. Mei Peng is a lecturer in sensory science in the Department of Food Science. With a research background in experimental psychology (psychophysics), Mei is interested in sensory, cognitive and behavioural factors driving people's food choices and intake. 

In particular, Mei focuses her research on individual differences in sensory processing and their links to pathological eating behaviours and obesity, using both behavioural and neuroimaging techniques. 

She has been recently awarded the Marsden Fast-Start funding to develop her research project on "Searching for multi-sensory fingerprints: a personalised index of hedonic eating" (2018 - 2020).

Mei's research specialities include: the human olfactory system, sensory neuroscience and psychophysical modelling of sensation and perception.
