I lead research investigating mechanism of action of probiotics and food ingredients on physiology using animal, tissue, and cell models via membrane receptors. Through the Smarter Lives MBIE Endeavour Research programme we investigate the ability of dairy foods to influence behaviour via the gut-brain axis. We explore the taste attributes of fermented foods such as yogurt through interactions between fermentation-derived peptides and human taste receptors for kokumi, umami and sweet tastants.
