The 12th International Conference on Chemical Structures (ICCS) will take place in 2022. It will continue a well-established conference series that begun in 1973 as a workshop on Computer Representation and Manipulation of Chemical Information sponsored by the NATO Advanced Study Institute and thereafter was held under its new name every third year starting in 1987. The 2022 conference will build on the experience of the past successful editions to offer a strong scientific program which covers all aspects of cheminformatics and molecular modeling, including for example structure-activity relationships, virtual screening, modeling metabolite networks, etc. Participants discuss research as well as relevant technological and algorithm developments in handling and visualization of chemical structure data, workflows for complex cheminformatic analysis and machine learning. The conference fosters cooperation among organizations and researchers involved in the increasingly interwoven fields of cheminformatics and bioinformatics and combines in-depth technical presentations with ample opportunities for one-on-one discussions with the presenters.
