The team

ChemSpider data quality is managed by a small team of full-time curators, who work to add new compounds, remove errors, and respond to user feedback. Our staff have extensive experience of both chemical data and practical chemistry.

As part of the Royal Society of Chemistry there are many people who contribute to the ongoing support and development of ChemSpider and many more who are involved with the Royal Society of Chemistry’s databases and cheminformatics resources.
