The Liberles Group (https://sites.temple.edu/liberles/) is looking for a new postdoctoral scientist to join us, in the areas of computational/mathematical molecular evolution and comparative genomics. We are open to students from various backgrounds who have a passion for studying questions about evolution. Ongoing research in the group is in areas including models for duplicate gene retention in genomes, in evolutionary systems biology for the context-dependent evolution of genes, and for protein evolution. The exact research topic is open to discussion. The Liberles Group is based at Temple University in Philadelphia, PA, USA. A strong preference is for a candidate who is willing and able to relocate to Philadelphia. Unfortunately, this is probably most practical for US citizens or researchers of other nationalities who are currently in the United States. Philadelphia offers a vibrant academic community, noted culinary and cultural opportunities, and a lower cost of living than other major northeastern cities. An ideal start date for the position would be January, 2027, but that is subject to negotiation. Candidates still finishing a Ph.D. with an expected completion in the next year are encouraged to apply. Funding will be guaranteed for a year and extension is possible by mutual agreement and available funding. Please send your CV, a cover letter describing your interest, and a reprint (or preprint) from your prior work that is most related to theoretical or computational molecular evolution/ comparative or population genomics or phylogenetics (please only send one paper).
