— ISMB/ECCB 2021 CompMS – Save the date & call for proposals — Dear colleagues, Please join us during the virtual ISMB/ECCB 2021 conference for the Computational Mass Spectrometry (CompMS)COSI session on July 25–27, 2021. Combining the annual Intelligent Systems for Molecular Biology (ISMB)and the European Conference on Computational Biology (ECCB), this is the world's largest bioinformatics/computational biology conference. Every year it brings together scientists from computer science, molecular biology, mathematics, statistics, and related fields and provides an intense multidisciplinary forum for disseminating the latest developments in bioinformatics/computational biology. The conference fosters fresh dialogues, collaboration and learning opportunities, and is a gathering which shapes the future of the field. With a focus on everyone’s safety, the ISMB/ECCB 2021 conference will be a virtual event. Moving the conference to a state of the art virtual interface will not change what attendees have come to expect from this conference. The virtual interface will only enhance the attendee experience and ensure that more people can enjoy it. At the heart of the scientific program are ISCB’s Communities of Special Interest (COSIs), enabling community involvement and bolstering ISMB/ECCB’s reputation as the leading conference in the field. The CompMS COSIpromotes the efficient, high quality analysis of mass spectrometrydata through dissemination and training in existing approaches and discussion of new, innovative approaches. The CompMS initiative aims to exploit synergies between different mass spectrometry-based application domains, in particular proteomics, metabolomics, and lipidomics. A strong scientific and technical program showcases the best international developments in bioinformatics and computational biology, making ISMB/ECCB 2021 a must attend event.
