After completing a PhD at the EGCE laboratory (Evolution and Ecology Division, supervised by M. Harry and F.

At the EGCE laboratory (Evolution and Genomes Team), I am currently working on comparative genomics of different strains of&nbsp;<strong>Hermetia illucens<\/strong>&nbsp;(Black Soldier Fly), an excellent model for domestication with a high potential for agro-industrial applications.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\" id=\"research-experience\">Research Experience<\/h1>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Evolution of chemosensory genes related to the transition from terrestrial to aquatic environments in beetles, using a comparative transcriptomics approach at ISYEB (Sorbonne University, MNHN, EPHE, CNRS, UA), supervised by Prof. Micha\u00ebl Manuel (Postdoctoral fellowship, June 2023 &#8211; Dec. 2024)<\/strong>\u00a0Assembly of transcriptomes of Adephaga beetles and annotation of chemosensory transcripts.
