Isabelle Arnold

Isabelle Arnold is Assistant Professor and Head of the Mucosal Immunology Group at the Institute of Experimental Immunology, University of Zürich, Switzerland. Isabelle obtained her PhD in Cancer Biology from the University of Zürich in 2011, before joining the laboratory of Prof. Fiona Powrie at the University of Oxford as a post-doctoral fellow, where she began to work on intestinal eosinophils. In 2015, Isabelle moved back to Switzerland and joined the Institute of Molecular Cancer Research at the University of Zürich as a junior group leader to investigate eosinophil responses to bacterial pathogens and in settings of colorectal cancer. In 2020, she was awarded an Eccellenza Professorial Fellowship from the Swiss National Science Foundation to pursue her research activities at the Institute of Experimental Immunology, where she is currently located. Isabelle is mostly interested in understanding how eosinophils contribute to local homeostatic and inflammatory processes in the gastrointestinal tract, and which signaling pathways drive their pleiotropic activities. Her pioneer work has uncovered several new functions for this elusive cell type in the regulation of Th1 immune responses, their bactericidal activity against intestinal pathogens as well as the promotion of anti-tumor responses in models of colorectal cancer.
