Arielle Planchette, PhD

Research Scientist
2207 Wc Portraits 004
Arielle’s main interest lies in exploring the gut-brain axis in health and disease with the aim of identifying potential diagnostic and therapeutic solutions. To do so, she brings a perspective of combining fundamental research questions with the development of advanced technologies.

Arielle Planchette joined the Wyss Center in May 2022 as a Research Engineer, then continued as Research Scientist in February 2024, bringing expertise in the physiological interactions between the gut and the brain and their relevance in neurodegenerative diseases. She plays a key role in the design of novel optogenetic and endomicroscopy technologies to study the enteric nervous system’s structure and connectivity.
Arielle holds a MRes in Synthetic Biology from University College London. She received her PhD in Bioengineering in 2022 from the École Polytechnique Fédérale de Lausanne (EPFL), where she studied the effect of gut microbiome modulation in a mouse model of Alzheimer’s disease and developed an experimental pipeline to perform large-scale 3D multi-modal fluorescence imaging of mouse intestinal sections.
