Complex Systems Chemistry is an emerging discipline that originated in Strasbourg, developing from the work of Professor Jean-Marie Lehn, Nobel Prize laureate in Chemistry and pioneer of the field. At the interface of chemistry, biology, materials sciences and nanosciences, the discipline has numerous applications in the fields of sustainable development (sustainable, biodegradable, self-repairing materials, etc.), health (nanomedicine, diagnostic tools, anti-pathogenic materials, etc.) and data processing (artificial intelligence, data storage, etc.)
