Ruth Ley, Max Planck Institute for Biology Tübingen, Germany

Prof. Ruth Ley is the Director of Department of Microbiome Science at the Max Planck Institute for Biology in Tübingen, Germany. She is a microbial ecologist who studies the diversity, evolution and function of the human gut microbiome. A major focus of her research has been the evolutionary relationships between humans and their gut microbes. She demonstrated that host genetics contributes to microbiome composition and identified heritable microbial taxa associated with metabolic health. Through large-scale comparative studies, she showed that many gut microbes share an evolutionary history with their hosts, providing evidence for long-term host-microbe associations and codiversification. Her laboratory has also uncovered molecular mechanisms of host-microbiome interaction, including immune evasion of flagellins produced by commensal gut bacteria, and the integration of microbially derived lipids into host metabolic pathways.

Jingyuan Fu, University Medical Center Groningen, The Netherlands

Prof.  Jingyuan Fu is a professor of systems medicine in the University Medical Centre Groningen, the Netherlands and an elected member of the Royal Netherlands Academy of Arts and Sciences (KNAW) and the Royal Holland Society of Sciences and Humanities (KHMW). She obtained a BSc in Biochemistry, a MSc in Biotechnology and Bioinformatics (cum laude), and a PhD in systems genetics (cum laude). Via this route she developed her research interest on host-microbe interactions in complex traits and diseases using integrative genomics approaches and aims to acquire a greater knowledge of how the human genome and the gut microbiome interact with each other and affect human health, in order to create better methods for disease prediction, prevention, and treatment. To accomplish this, her study combines with large-scale genetic and microbial association studies in big groups of individuals with functional studies using advanced bacterial culturing and organ-on-chip technologies.

Sean Gibbons, Institute for Systems Biology, USA

Dr Sean Gibbons earned his PhD in biophysics from the University of Chicago in 2015. He completed his postdoctoral work at MIT in 2018 and is currently Associate Professor at the Institute of Systems Biology, Seattle, USA.

His lab studies the ecology and evolution of microbial communities. In particular, Sean is interested in how host-associated bacterial communities influence the health and wellness of the host organism. His group designs computational and wet-lab tools for studying these complex systems. Ultimately, the Gibbons Lab aims to develop strategies for engineering the ecology of the gut microbiome to improve human health.

Jens Walter, University of Cork, Ireland

Prof. Jens Walter is Professor of Ecology, Food and the Microbiome at University College Cork and a Principal Investigator at APC Microbiome Ireland. He trained in food science and microbiology at the University of Hohenheim, Germany, before undertaking postdoctoral research in New Zealand and the United States. He began his independent career at the University of Nebraska–Lincoln, later moving to the University of Alberta, Canada, where he held a prestigious Campus Alberta Innovates Program (CAIP) Chair, before relocating to Ireland. He is currently supported by a Science Foundation Ireland Research Professorship, one of the country’s most competitive research awards.

His research lies at the interface of evolutionary ecology of the gut microbiome and human nutrition, with a focus on the processes that shape host–microbiome interactions and how these can be leveraged to improve human health. He is internationally recognized for integrating ecological theory with microbiome science and for leading controlled human intervention studies investigating dietary and microbial strategies to modulate the gut microbiome. This work includes the development of the Non-Industrialized Microbiome (NiMe) diet, a translational approach aimed at restoring microbiome function through dietary change.
