Systematists and comparative biologists commonly want to make statements about
relationships among taxa that have never been collectively included in any single …

Supertrees result from combining many smaller, overlap** phylogenetic trees into a
single, more comprehensive tree. As such, supertree construction is probably as old as the …

The idea that all life on earth traces back to a common origin dates back at least to Charles
Darwin's Origin of Species. Ever since, biologists have tried to piece together parts of this …

Background Several phylogenetic approaches have been developed to estimate species
trees from collections of gene trees. However, maximum likelihood approaches for …

Demarcation of the border between solvable and unsolvable distributed tdis under various
models is the holy grail of the theory of distributed computing. Oneof the most celebrated of …

We study the problem of learning a latent tree graphical model where samples are available
only from a subset of variables. We propose two consistent and computationally efficient …

This thesis analyses the conception and measurement of complexity and then applies it to
some aspects of formal languages. It starts with a review of the philosophy of modelling. It …

Background Species tree estimation is challenging in the presence of incomplete lineage
sorting (ILS), which can make gene trees different from the species tree. Because ILS is …

A comprehensive account of both basic and advanced material in phylogeny estimation,
focusing on computational and statistical issues. No background in biology or computer …

The estimation of species trees using multiple loci has become increasingly common.
Because different loci can have different phylogenetic histories (reflected in different gene …
