About

Associate Professor Mei Peng specialises in Sensory Science and Food Psychology. With a background in Experimental Psychology, Mei investigates how sensory perception, cognitive traits, and emotional factors shape eating behaviours and broader health outcomes. Her work draws on a multidisciplinary approach—combining behavioural science, psychophysics, and neuroimaging—to understand how individuals experience food, how preferences develop, and how these processes vary across people and life stages.

Mei leads the Sensory Neuroscience and Nutrition Laboratory, which specialises in large-scale, multi-method research projects supported by prestigious national and international funding, including three Marsden Fund grants. Her current Marsden-funded project (2022–2025) investigates how sensory shifts influence dietary patterns using advanced neuroimaging and cognitive assessments. She also leads and co-leads a few HRC-funded initiatives devising support for improving dietary quality for diverse populations, such as obesity, neurodevelopmental diverse, and ageing population.

In 2020, Mei established the ENERGY Longitudinal Study Cohort—Aotearoa New Zealand’s first pregravid longitudinal study—tracking behavioural, metabolic, and neural-sensory changes related to pregnancy.

Mei teaches across undergraduate and postgraduate levels and has contributed to the development of food psychology as an area of study, offering students a unique lens into how psychological and cultural factors influence food-related decisions. Her teaching is informed by her ongoing research and commitment to cross-disciplinary learning.

She is a founding member of the Australasian Sensory Professional Network, convenor of the NZ-Australian Sensory Symposium, and serves on the editorial board of Food Quality and Preference. Her work is deeply grounded in principles of equity, diversity, and Vision Mātauranga, and she actively supports culturally responsive research partnerships with Māori communities.

Research interests

Mei’s research examines the cognitive, emotional, and sensory mechanisms underlying food perception and eating behaviour. She is particularly focused on how inter-individual and cross-cultural differences in sensory processing relate to broader health outcomes, including obesity, food neophobia, and depression.

Research themes include:

Sensory fingerprints and individual differences in multisensory integration
Mental imagery and its role in eating behaviour and food neophobia
Impact of pregnancy and hormonal changes on taste, smell, and dietary choices
Psychophysical modelling of flavour perception
Cultural and environmental influences on food perception in Aotearoa and beyond
AI-assisted diagnosis of sensory-related feeding disorders in neurodiverse children

Her research is supported by the Marsden Fund, the Health Research Council (HRC), CoRE funding, and the Fulbright Programme.
