We are looking for a postdoctoral scientist to work on codes for the storage of digital information in synthetic DNA sequences at the European Bioinformatics Institute (EMBL-EBI) located on the Wellcome Trust Genome Campus near Cambridge in the UK. A postdoctoral scientist is sought to work for three years on the information and coding theory aspects of the Coding Theory and Synthetic Biology project. DNA is a stable chemical compound that is the "hard drive" of life, encoding the genome of all living organisms and copied from generation to generation over evolutionary timescales. The European Bioinformatics Institute (EBI), Europe's leading centre for bioinformatics services and research, is heading a research project on the use of synthetically created DNA for storing and recovering digital information. Following our successful "DNA-storage" experiment's publication and media interest, we now hold a grant to further develop the methods and technologies that a future DNA-based information archival system will require. Although our initial experiment used a very simple code to represent digital information in the 4-letter alphabet of DNA, a robust future scheme will require greater error tolerance through error-correcting codes. The properties of the channel over which information will be sent (including DNA synthesis, copying, storage, transportation and reading or 'sequencing') are non-standard, and new channel constraints are expected to emerge over the duration of the project in response to the requirements of our laboratory collaborators. The postdoctoral fellow will work with Nick Goldman, Ewan Birney and experimental collaborators at the neighbouring Sanger Institute to design and implement codes for synthetic DNA. The codes will be optimized for this non-standard channel, and adapted according to the developing requirements of a practical DNA-based digital information archive system.
