We invite abstract submissions for talks and/or posters to the Evolution and Comparative Genomics (EvolCompGen) track at ISMB on July 12-16 in Washington DC. Describe your recent work on 1-2 pages and submit before the deadline on Friday April 9 (midnight anywhere on earth)! Abstract submission site: https://www.iscb.org/ismb2026/call-for-submissions/abstracts More about the meeting: Intelligent Systems in Molecular Biology (ISMB) is the flagship conference of the International Society of Computational Biology. In 2026, the meeting will be held July 12-16 in Washinton DC. Conference web site: https://www.iscb.org/ismb2026/home More about EvolCompGen: The EvolCompGen "community of special interest" (COSI) organizes a track at ISMB each year on topics at the interface between evolution, comparative genomics, and computational biology. Our sessions have high attendance and showcase contributions in genome evolution; genome rearrangements; genomic variation, diversity, and dynamics; the evolution of protein structure and function; cancer evolution and phylogenetics; population genomics; mutational models; phylogenetics and the comparative method; phylogenomics; phylodynamics; pangenomics and microbial evolution; and metagenomics.
