I am a Principal Scientist and immunologist specializing in organoid models, stem cell biology, and drug screening. At the Jaulin Lab (Gustave Roussy Hospital), I study immunotherapy toxicity and develop 3D models to investigate epithelial barrier function and immune–epithelial interactions. Previously at the Imagine Institute, I modeled rare kidney diseases using organoids to uncover mechanisms and therapeutic targets, following earlier work on stem cell–derived cardiac tissues and immune responses at Mount Sinai (New York) and Hôpital Necker (Paris). My research, published in several journals, reflects my passion for using organoid technology to advance drug discovery and precision medicine.

Fanny Jaulin, Ph.D
Group Leader
I have always been fascinated by cell shape, multicellular architecture and how this relates to tissue function. I did my PhD studies in the lab of Jean-Paul Borg working on protein complexes setting–up apico-basolateral polarity in normal epithelial tissues. As a postdoctoral fellow in New York, I trained in the labs of Geri Kreitzer (Weill Medical College) and Alan Hall (MSKCC) developping 3D cell biology and microscopy-based approaches to decrypt the role of the cytoskeleton in the morphogenesis of epithelial cells.
It is through the INSERM/CNRS ATIP-AVENIR award for young investigators that I have established my lab at the Gustave Roussy Institute. I now coordinate a team of talented scientists and clinicians to unlock some of the mysteries behind the metastatic progression of digestive cancers.
