A consistent least-squares criterion for calibrating edge lengths in phylogenetic networks
Jingcheng Xu, Cécile Ané
In phylogenetic networks, it is desirable to estimate edge lengths in substitutions per site or calendar time. Yet, there is a lack of scalable methods that provide such estimates.…

A dissimilarity measure for semidirected networks
Michael Maxfield, Jingcheng Xu, Cécile Ané
Semidirected networks have received interest in evolutionary biology as the appropriate generalization of unrooted trees to networks, in which some but not all edges are directed.…

Leveraging graphical model techniques to study evolution on phylogenetic networks
Benjamin Teo, Paul Bastide, Cécile Ané
The evolution of molecular and phenotypic traits is commonly modelled using Markov processes along a phylogeny. This phylogeny can be a tree, or a network if it includes reticulati…
