Setup a bioinformatics platform dedicated to insect pest genomics using open-source software. Its main goals are to supply the needs on automatically or manually annotation, genome browsing or genome comparative analyses as well as to write sophisticated procedures such as ontology driven annotation pipelines and help and teach users and curators by organizing workshop and seminars

Support to various genomics research activities (genome annotation, physical and genetic maps, miRNA identification, comparative genomics and evolution)
