IEEE-BIBM 2015 in Washington, D.C. The rapid accumulation of macromolecular structures presents a unique set of challenges and opportunities in the analysis, comparison, modeling, and prediction of macromolecular structures and interactions. This workshop aims to bring together researchers with expertise in bioinformatics, computational biology, structural biology, data mining, optimization and high performance computing to discuss new results, techniques, and research problems in computational structural bioinformatics. CSBW invites high quality original papers and posters on developments in computational problems relating to molecular structure. Authors of accepted papers will be provided approximately 15-20 minutes to provide an oral summary of their work, with time for questions. Please refer to the website below for details on format and submission. At least one author of an accepted paper is required to register for the workshop to present the paper. Registration to CSBW is complementary with registration to IEEE-BIBM 2015.
