Sébastien Wagner

Sébastien Wagner is a researcher affiliated with the Institut Pasteur in Paris, focusing on neuroscience with an emphasis on olfactory system dysfunction in neurological and psychiatric conditions. His work spans projects like SMELLPARK, which investigates nasal dysbiosis in Parkinson's disease, and SOCSET, studying long-COVID olfactory and cognitive symptoms. He contributes to understanding how viral infections (e.g., SARS-CoV-2) and neuroinflammatory mechanisms disrupt sensory processing and brain function.

• Projects: SMELLPARK, SOCSET, Congenital CMV CNS Impact
• Methodology: Developed tools like the sono-olfactometer for olfactory testing in rodents and advanced optogenetic techniques for neuronal stimulation.
• Research Trends: His recent publications highlight gut-brain communication via Nod2 receptors (2022), amygdala circuit disruptions in depression (2024), and SARS-CoV-2's role in persistent anosmia (2021). Sub-fields include neuroimmunology, neurodegeneration, and affective neuroscience.
