Our Amazing Team
Prof. Dr. Emma Slack
Group Leader
Emma is a British/Swiss scientist who trained in Cambridge, London, Hamilton (Ontario) and Bern before joining the ETH Zürich. She is now a Professor of Mucosal Immunology at the Department of Health Sciences and Technology, as well as at the Sir William Dunn School of Pathology, at the University of Oxford. She believes that difficult scientific problems, like understanding how the immune system in the intestine can influence microbiome composition and function, require a creative team of individuals collaborating closely across disciplines to solve them. These brilliant scientists need a safe, happy space to push the boundaries of knowledge, where they know that we are all there to support each other. So, while she still likes to get into the lab and get involved, she is also committed to leading a research group that reflects these values.
