Phylogenetics Meets Population Genetics: From Trees to Networks

Phylogenetics and population genetics have studied evolutionary history at different scales: relationships among species over long timescales versus processes within species over shorter ones. Genome-scale data are blurring these boundaries and revealing non-treelike evolution driven by recombination, gene flow and hybridization. This workshop brings together mathematicians, statisticians and biologists to explore the shared foundations of both fields and develop integrative approaches to modelling and inference, with a particular focus on connections between ancestral recombination graphs and phylogenetic networks, which are mathematically equivalent structures for representing reticulate evolutionary histories. A tutorial day establishes common ground, followed by focused working-group sessions and research presentations at the interface of stochastic processes, graph theory and evolutionary biology. Participation is by registration and acceptance through NITMB's workshop form. Participants based more than 50 miles from NITMB register by 5 February 2027; NITMB covers their travel, lodging, breakfast and lunch. Local participants (within 50 miles) register by 15 March 2027.
