The WABI 2011 workshop was part of the six ALGO 2011 conference meetings, which, in addition to WABI, included ESA, IPEC, WAOA, ALGOSENSORS, and ATMOS. WABI 2011 was hosted by the Max Planck Institute for Informatics, and sponsored by the European Association for Theoretical Computer Science (EATCS) and the International Society for Computational Biology (ISCB). See https://algo2011.mpi-inf.mpg.de/ for more details. The Workshop in Algorithms in Bioinformatics highlights research in al- gorithmic work for bioinformatics, computational biology, and systems biology. The emphasis is mainly on discrete algorithms and machine-learning methods that address important problems in molecular biology, that are founded on sound models, that are computationally efficient, and that have been implemented and tested in simulations and on real datasets. The goal is to present recent research results, including significant work-in-progress, and to identify and explore direc- tions of future research. Original research papers (including significant work-in-progress) or state-of- the-art surveys were solicited for WABI 2011 in all aspects of algorithms in bioinformatics, computational biology, and systems biology. In response to our call, we received 77 submissions for papers and 30 were accepted. In addition, WABI 2011 hosted a distinguished lecture by Vincent Moulton, of the University of East Anglia, UK. We would like to sincerely thank the authors of all submitted papers and the conference participants. We also thank the Program Committee and their sub-referees for their hard work in reviewing and selecting papers for the workshop. We would especially like to thank Bernard Moret for all his advice and sup- port in carrying out the role of being Co-chairs, as well as EasyChair for making the management of the submissions to WABI such an easy process. Thanks once again to all who participated in making WABI such a success in 2011. For us it has been an exciting and rewarding experience.
