*Postdoctoral position in the genomics of adaptation at the Natural History Museum in Paris * A *two-year postdoc* is available for an independent, creative and motivated post-doc to work on the*genomics of adaptation and hybridization in mimetic butterflies*. The postdoc will work with Violaine Llaurens and Mathieu Joron at the Institute of Systematics, Evolution and Biodiversity at the National Museum of Natural History in Paris (France). Our group is interested in the ecological and genetic changes associated with adaptive wing color patterns in Heliconius butterflies. We are particularly interested in genomic architectures and the formation of a supergene controlling a spectacular wing pattern polymorphism associated with mimicry in the species Heliconius numata. This supergene is characterized by complex inversion polymorphism forming long haplotypic blocks, and a dominance hierarchy of alleles. This adaptive architecture appears to have evolved in response to selection for multiple mimicry forms, but how the variants corresponding to accurate mimetic phenotypes differentiate is still a puzzle. Processes such as ancestral polymorphism, large size mutations, or introgression may be involved, and some seem to be supported by our currently available resequence and transcriptome datasets. Our project aims at understanding the evolutionary origins and the functional basis of this genetic architecture in this lineage and how this relates to closely-related species. The postdoc will be in charge of developing population genomics approaches towards the dissection of the history of inversion polymorphism and recombination in H. numata and close allies, and transcriptomic/expression analyses to understand the functional basis of supergene expression. Butterflies in the genus Heliconius have become a prominent group of insects for evolutionary genomics, with a rich evolutionary radiation, a reference genome, and vigorous collaboration between labs within the Heliconius consortium (heliconius.org ). This project, funded by a grant from the Agence Nationale de la Recherche (ANR), will provide ample opportunity for the postdoc to develop his/her own original research ideas. Candidate profile: A Phd in evolutionary biology, with a strong interest in population genomics. Experience with whole genome or transcriptome datasets would be appreciated. Income and Starting Date: Net salary will be around 2500 euros net per month, depending on experience. Starting date in the spring 2014 is desired but is negotiable. Application deadline: Send us a CV and a cover letter, and the names of two references by 28th February 2014 to the following addresses: [email protected] and [email protected] More information: isyeb.mnhn.fr/joron isyeb.mnhn.fr/violaine-llaurens isyeb.mnhn.fr/mathieu-joron -- Mathieu Joron Institut de Systématique, Evolution, et Biodiversité UMR 7205 CNRS MNHN UPMC EPHE Muséum National dHistoire Naturelle CP50, 45 Rue Buffon, 75005, Paris Tel: 0033-(0)1-40-79-80-92 Mob: 0033-(0)6-28-28-11-88 Fax: 0033-(0)1-40-79-33-42 isyeb.mnhn.fr/joron
