The Liberles Group is looking for a new postdoctoral scientist to join us, in the areas of computational/mathematical molecular evolution and comparative genomics. We are particularly interested in students with a joint background in mathematics (particularly probability theory and stochastic processes) and biology (particularly evolution and genetics). Those trained in math should have some formal training in biology and those trained in biology should have demonstrable quantitative expertise. We are also open to students from physics and other quantitative backgrounds who are grounded in biology. 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 to relocate to Philadelphia. 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).
