Interests
We are interested in understanding the mechanisms underlying the diet-gut microbiota-brain axis, and how gut microbes can influence brain function in health and disease. We employ a range of different in vitro neural and neurovascular models to study the pharmacology of gut microbe-derived mediators upon the brain, allowing identification of target pathways and systems for potential therapeutic intervention.Publications
