Advancing ancestry inference for studies integrating ancient & modern human genomes<\/h4>\n\n\n\n
My project aims to advance methods for ancestry inference by integrating ancient and modern human genomic data. Mixed-membership clustering algorithms, widely used in population genetics, face challenges when applied to datasets with temporal and sample-size imbalances, particularly involving ancient DNA. I will investigate the robustness of clustering outputs under varying conditions and develop improved strategies for aligning clustering results and inferring allele frequency trajectories over time, with applications to
studying genetic targets of selection following the Neolithic expansion. Additionally, I will study identity-by-descent (IBD) sharing in ancient genomes to understand recent genealogical connections and their implications for demographic inference, with applications to the Bantu expansion. Applying new approaches for studying IBD sharing from my group to ancient DNA will enable tracking of inherited segments and their ancestral origins, offering insights into historical mating patterns and population structure. As a Human Past Residential
Fellow, I will collaborate with colleagues at the Center to refine these tools, with particular focus on the Neolithic and Bantu expansions, ultimately enhancing our understanding of human evolutionary history.<\/p>\n<\/div>\n<\/div>\n\n\n\n

The fellowship programme is an initiative by the Center for the Human Past, administered by the Swedish Collegium for Advanced Studies (SCAS). It is designed to foster a collaborative environment where early-stage and established scholars can converge across three disciplines, archaeology, population genetics and historical linguistics to explore the shared history of the world\u2019s populations over the past 10,000 years.<\/p>\n\n\n\n
