Bayesian Inference of Phylogenetic Networks
… of a species tree. The field of computational phylogenetics has witnessed an explosion in the development of methods for species tree inference under the MSC, owing mainly to the accumulating evidence of incomplete lineage sorting in phylogenomic analyses. However, the evolutionary history of a …

Constructing Phylogenetic Networks based on Trinets
Abstract The motivation of phylogenetic analysis is to discover the evolutionary relationships between species, with the broader aim of understanding the origins of life. Our understanding of the molecular character- istics of species through DNA sequencing permanently changed the approach to …

Phylogeny Inference in the Presence of Incomplete Lineage Sorting, Gene Duplication and Loss and Hybridization
… and statistical methods for inferring phylogenetic networks were developed. Birth-death models of gene evolution have also been introduced to capture gene duplications and losses, and species tree inference methods that utilize them have been developed. In this thesis, I address two …

Inference of parsimonious species phylogenies from multi-locus data
… this framework, we extend the MDC criterion to phylogenetic networks, and use it to propose a heuristic to detect hybridization despite lineage sorting. Empirical results on a simulated and a yeast data set show its promising performance, as well as several directions for future research.

Mitochondrial DNA in ancient human populations of Europe.
… were compared by haplotype sharing analysis, phylogenetic networks, Analysis of the Molecular Variance and coalescent simulations. The sequencing of a whole mitochondrial genome in a north east European Mesolithic individual lead to defining a new branch within the human mitochondrial tree. …
