TWO YEAR POSTDOCTORAL POSITION IN EVOLUTIONARY GENOMICS AT UNIVERSITY OF CALIFORNIA, RIVERSIDE The Purcell lab at the University of California, Riverside is seeking a motivated Postdoctoral Fellow to lead research on the evolution of a supergene polymorphism shared across hundreds of ant species and 20 MY of evolutionary history. The focal supergene is associated with complex social traits, including variation in ant colony queen number, sex allocation, and queen size. Please check out some of our recent publications for more information: https://scholar.google.com/citations?user=JFmZEsIAAAAJ&hl=en&oi=ao We are also interested in investigating the evolution of chromosome structure, especially in regions with long-term recombination suppression. The successful candidate will be able to contribute to the analysis of a large, multi-species genomic dataset (including short-read and long-read WGS, RADseq, and RNAseq) and to writing resulting scientific articles. Training is available, but prior experience with genetics, genomics, and bioinformatics is preferred. Applicants with prior research experience studying supergenes, inversions, sex chromosome evolution, and/or social arthropods are also preferred. Members of the research group and department are friendly and collaborative, and we are looking for a team member who will appreciate regular interactions with labmates and colleagues. The ideal candidate will be able to: - Analyze genomic data on a high performance computing cluster - Interact and share their knowledge with graduate and undergraduate researchers - Identify new research avenues to pursue with available data and - Write scientific articles The postdoctoral fellow would also have the opportunity, if desired, to participate in outreach and to formally mentor undergraduate researchers. The fellow would join an active, collegial institution with a vibrant community of evolutionary genomics researchers spanning multiple departments. If interested, please send a cover letter describing your prior experience, interests, and potential fit to the position along with your CV and contact information for two referees to Jessica at jpurcell@ucr.edu. Review of application materials will begin on November 3, 2025, but applications will be considered until the position is filled. The preferred start date for this two year position is January 2026, but there may be some flexibility for the ideal candidate.
