Louise Larsson completed her MSc in biotechnological engineering at KTH Royal Institute of Technology in Sweden before joining ETH Zurich as a doctoral student co-supervised by Prof Médéric Diard and Prof Emma Slack. She is working on developing precise tools for engineering the gut microbiota in situ to reduce the production of harmful microbial metabolites for symptom amelioration in children with inborn errors of metabolism. Furthermore, she is also working on a phage therapy approach to exclude encapsulated pathogens from the gut environment in order to prevent sepsis.
