The Evolutionary Genomics of Sex lab at Vrije Universiteit Brussel (Brussels, Belgium) is hiring 2 postdoctoral researchers to investigate the evolution, genetic mechanism and genomic signatures of sex chromosomes in various frog lineages. Our lab explores how sex chromosomes and sex-determining systems evolve across eukaryotes, and how and why they are stable in some lineages (i.e. mammals, birds) but remarkably labile in others (amphibians, fishes, reptiles, insects and flowering plants). These positions are part of an ERC-funded project aiming to understand the genomic signatures of both differentiated and undifferentiated sex chromosomes in species with male (XX/XY) and female (ZW/ZZ) heterogamety, using an integrative approach combining comparative and functional genomics, population genetics, molecular evolution and genetics, cytogenetics, and fieldwork. Position 1: Comparative & Evolutionary Genomics We are looking for a highly motivated postdoctoral researcher with a PhD in bioinformatics, evolutionary genomics, computational biology or a closely related field. The ideal candidate has strong experience in: High-throughput sequencing workflows (WGS, RNA-seq, RAD-seq) Genome assembly and annotation, transcriptomic Comparative genomics and population genomics analyses Proficient coding in Python, R, Bash, Perl, (or equivalent) Fieldwork experience is a plus. Responsibilities include curating and maintaining lab codebases, leading genomics projects, mentor Master's, bachelor's and practical-course students. Strong communication skills and a collaborative team spirit are essential. Fieldwork experience is a plus. Teaching opportunities are available if desired. Position 2: Molecular and Evolutionary Genetics We are seeking a highly motivated candidate with a PhD in evolutionary genetics or molecular evolution, with solid experience with diverse molecular and functional techniques, Responsibilities include: Leading ongoing research projects Help PI coordinate the molecular lab Mentoring Master's, Bachelor's, and practical-course students Opportunity to develop independent research projects Field experience is a plus. Teaching opportunities are available if desired. Application instructions: Applicationsshould be emailed to Prof. Wen-Juan Ma (wen-juan.ma@vub.be) and include: (1) a CV (2) a cover letter outlining your qualifications, research interests and career goals (3) Contact details for three references. Application deadline: Rolling, until the positions are filled. Each position is offered as a 2-year contract, with renewal on an annual basis. Support will be provided for applying to independent postdoctoral fellowships. Informal inquiries are welcome (wen-juan.ma@vub.be). The positions are available immediately. The Ma lab is part of Ecology, Evolution and Genetics (bDIV) research group and funded by a prestigious ERC starting grant.
