Vilma Liikonen, MSc, is a doctoral researcher at the University of Finland, focusing on diet-gut-brain interactions. Her research investigates the effects of cereal-based foods on gut microbiota composition and related metabolic pathways using clinical intervention studies and multi-omics approaches. Her work aims to improve understanding of how cereal consumption modulates gut microbiota and host metabolism, and how processing of these foods, particularly fermentation, may influence the effects.
